Since `goog.getMsg` does not process ICUs (post-processing is required via goog.i18n.MessageFormat, https://google.github.io/closure-library/api/goog.i18n.MessageFormat.html) and placeholder format used for ICUs and regular messages inside `goog.getMsg` are different, the current implementation (that assumed the same placeholder format) needs to be updated. This commit updates placeholder format used inside ICUs from `{$placeholder}` to `{PLACEHOLDER}` to better align with Closure. ICU placeholders (that were left as is prior to this commit) are now replaced with actual values in post-processing step (inside `i18nPostprocess`).

`i18nStart` was calling `allocExpando` even if there was 0 new variable created.
This created a new expando instruction with the value 0 which was later interpreted as the start of a new expando block instead of just skipping 0 instructions.

Currently the `placeholders` parameter inside `i18nLocalize` is defaulted to `{}`, which means that we'll always hit the `Object.keys` call below. Since it's very likely that we won't have placeholders in the majority of strings, these changes add an extra guard so that we don't hit it on every invocation.

`TView.firstChild` was defined as the first node with index 0, but when we use runtime i18n then the instruction `i18nStart` can be the one with index 0 and the first node will be index 1 or more.

A directive input that doesn't use a binding is triggered during the creation phase. But this was only executed at the first template pass, and not on subsequent ones.

When translated content was projected, all of the content was reappended, even the placeholders that had been removed in the translation.
To avoid that we added a new flag on `TNode` that specifies that a node is detached, in which case it should be ignored by the projection.

Added a new syntax for projections (`¤` will represent `ng-content` nodes) so that we can treat them specifically.
When we enter an i18n block with the instruction `i18nStart`, a new `delayProjection` variable is set to true to prevent the instruction `projection` from projecting the nodes. Once we reach the `i18nEnd` instruction and encounter a projection in the translation we will project its nodes.
If a projection was removed from a translation, then its nodes won't be projected at all.
The variable `delayProjection` is restored to `false` at the end of `i18nEnd` so that it doesn't stop projections outside of i18n blocks.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

There is an encoding issue with using delta `Δ`, where the browser will attempt to detect the file encoding if the character set is not explicitly declared on a `<script/>` tag, and Chrome will find the `Δ` character and decide it is window-1252 encoding, which misinterprets the `Δ` character to be some other character that is not a valid JS identifier character

So far using runtime i18n with ivy meant that you needed to use Closure and `goog.getMsg` (or a polyfill). This PR changes the compiler to output both closure & non-closure code, while the unused option will be tree-shaken by minifiers.
This means that if you use the Angular CLI with ivy and load a translations file, you can use i18n and the application will not throw at runtime.
For now it will not translate your application, but at least you can try ivy without having to remove all of your i18n code and configuration.

Dynamic nodes are created at the end of the view stack, but we were removing all the placeholders between `i18nStart` and the last created node index, instead of removing everything between `i18nStart` and `i18nEnd`.

I18n can change the order of the nodes, or insert new dynamic nodes. When that happens it can break the existing links (`TNode.next`) or even create loops:
```
div1 → div2 → div3 → div4 → div5
```
Can become:
```
div1 → div4 → div2 → div3 div5

PR Close#28461
i18n instructions create text nodes dynamically and save them between bindings and the expando block in `LView`. e.g., they try to create the following order in `LView`.
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando (dirs, injectors) -- |
```
Each time a new text node is created, it is pushed to the end of the array and the `expandoStartIndex` marker is incremented, so the section begins slightly later. This happens in `allocExpando`.
This is fine if no directives have been created yet. The end of the array will be in the "dynamic text node" section.
| -- elements -- | -- bindings -- | -- dynamic i18n text -- |
However, this approach doesn't work if dynamic text nodes are created after directives are matched (for example when the directive uses host bindings). In that case, there are already directives and injectors saved in the "expando" section. So pushing to the end of `LView` actually pushes after the expando section. What we get is this:
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando -- | -- dynamic i18n text-- |
```
In this case, the `expandoStartIndex` shouldn't be incremented because we are not inserting anything before the expando section (it's now after the expando section). But because it is incremented in the code right now, it's now pointing to an index in the middle of the expando section.
This PR fixes that so that we only increment the `expandoStartIndex` if nothing was pushed into the expando section.

Prior to this change the postprocess step relied on the order of placeholders combined in one group (e.g. [�#1�|�*1:1�]). The order is not guaranteed in case we have nested templates (since we use BFS to process templates) and some tags are represented using same placeholders. This change performs postprocessing more accurate by keeping track of currently active template and searching for matching placeholder.

There were two issues with multiple ICU expressions in the same i18n block:
- the regexp that was used to parse the text wasn't able to handle multiple ICU expressions, I've replaced it with parsing the text and searching for brackets (which is what we ended up doing in the end anyway)
- we allocate node indexes for nodes generated by the ICU expressions which increases the expando value, but we would create the nodes for those cases during the update phase. In the mean time we would create some nodes during the creation phase (comment nodes for ICU expressions, text nodes, ...) with an auto increment index. This means that any node created after an ICU expression would get the following index value, but the ICU case nodes expected to use the same index as well... There was a mismatch between the auto generated index, and the expected index which was causing problems when we needed to select those nodes for updates later on. To fix it, I've added the expected node index to the list of mutate codes that we generate, and we do not use an auto increment value anymore.
