Depending on which placeholders the translation uses, there are some legitimate cases where we might not use all placeholder replacements in `i18nPostprocess`. For example if some of the placeholders of the original messages have been removed in the translation.

With Ivy, injecting a `ViewContainerRef` for a `<ng-container>` element
results in two comments generated in the DOM. One comment as host
element for the `ElementContainer` and one for the generated `LContainer`
which is needed for the created `ViewContainerRef`.
This is problematic as developers expect the same anchor element for
the `LContainer` and the `ElementContainer` in order to be able to move
the host element of `<ng-container>` without leaving the actual
`LContainer` anchor element at the original location.
This worked differently in View Engine and various applications might
depend on the behavior where the `ViewContainerRef` shares the anchor
comment node with the host comment node of the `<ng-container>`. For
example `CdkTable` from `@angular/cdk` moves around the host element of
a `<ng-container>` and also expects embedded views to be inserted next
to the moved `<ng-container>` host element.

The `flatten` function used `concat` and `slice` which created a lot of intermediary
object allocations. Because `flatten` is used from query any benchmark which
used query would exhibit high minor GC counts.

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 back to the frog eyes we go.

This is the first refactor PR designed to change how styling bindings
(i.e. `[style]` and `[class]`) behave in Ivy. Instead of having a heavy
element-by-element context be generated for each element, this new
refactor aims to use a single context for each `tNode` element that is
examined and iterated over when styling values are to be applied to the
element.
This patch brings this new functionality to prop-based bindings such as
`[style.prop]` and `[class.name]`.
PR Close#30469
In View Engine, we would simply ignore host style bindings on template nodes. In Ivy,
we are throwing a "Cannot read length of undefined" error instead. For backwards
compatibility, we should also ignore these bindings rather than blowing up.

Currently in Ivy `NgModule` registration happens when the class is declared, however this is inconsistent with ViewEngine and requires extra generated code. These changes remove the generated code for `registerModuleFactory`, pass the id through to the `ngModuleDef` and do the module registration inside `NgModuleFactory.create`.
This PR resolves FW-1285.

This is the final patch to migrate the Angular styling code to have a
smaller instruction set in preparation for the runtime refactor. All
styling-related instructions now work both in template and hostBindings
functions and do not use `element` as a prefix for their names:
BEFORE:
elementStyling()
elementStyleProp()
elementClassProp()
elementStyleMap()
elementClassMap()
elementStylingApply()
AFTER:
styling()
styleProp()
classProp()
styleMap()
classMap()
stylingApply()
PR Close#30318
This patch removes all host-specific styling instructions in favor of
using element-level instructions instead. Because of the previous
patches that made sure `select(n)` worked between styling calls, all
host level instructions are not needed anymore. This patch changes each
of those instruction calls to use any of the `elementStyling*`,
`elementStyle*` and `elementClass*` styling instructions instead.
PR Close#30336
This patch is one commit of many patches that will unify all styling instructions
across both template-level bindings and host-level bindings. This patch in particular
removes the `elementIndex` param because it is already set prior to each styling
instruction via the `select(n)` instruction.

Currently, in jit mode, `ngInjectableDef`, `ngDirectiveDef`, `ngPipeDef` and `ngModuleDef` use `ng://`,
which display them in the top domain in Chrome Dev Tools, whereas `ngComponentDef` uses `ng:///` which display components in a separate domain.
You can currently see:
```
AppModule
UserService
ng://
|_ AppComponent
|_ template.html
|_ AppComponent.js
...
```
This commits replaces all `ng://` with `ng:///` to display every Angular entity in the `ng://` domain.

This patch breaks up the existing `elementStylingMap` into
`elementClassMap` and `elementStyleMap` instructions. It also breaks
apart `hostStlyingMap` into `hostClassMap` and `hostStyleMap`
instructions. This change allows for better tree-shaking and reduces
the complexity of the styling algorithm code for `[style]` and `[class]`
bindings.

In the existing implementation the `elementPropertyInternal` function (meant to
set element properties) was executed even if a bound value didn't change. The
`elementPropertyInternal` was inspecting the incoming value and after comparing it
to `NO_CHANGE` - exiting early. All in all it meant that we were unnecessarily
invoking the `elementPropertyInternal` function for cases where bound value didn't
change.
Based on my bencharks (running change detection without any model update in a tight
loop) this unnecessary function call was causing ~5% slowdown in the change detection
process.

Ivy uses R3Injector, but we are currently pulling in both the StaticInjector
(View Engine injector) and the R3Injector when running with Ivy. This commit
adds an ivy switch so calling Injector.create() pulls in the correct
implementation of the injector depending on whether you are using VE or Ivy.
This saves us about 3KB in the bundle.

The `renderStringify` function is used in a lot of performance-sensitive places, however it contains a megamorphic read which is used primarily for error messages. These changes introduce a new function that can be used to stringify output for errors and removes the megamorphic read from `renderStringify`.

Fixes view and content queries not being inherited in Ivy, if the base class hasn't been annotated with an Angular decorator (e.g. `Component` or `Directive`).
Also reworks the way the `ngBaseDef` is created so that it is added at the same point as the queries, rather than inside of the `Input` and `Output` decorators.
This PR partially resolves FW-1275. Support for host bindings will be added in a follow-up, because this PR is somewhat large as it is.

Previously, we had a bug where directive matching could fail if the directive
attribute was bound and followed a certain number of classes. This is because
in the matching logic, we were treating classes like normal attributes. We
should instead be skipping classes in the attribute matching logic. Otherwise
classes will match for directives with attribute selectors, and as we are
iterating through them in twos (when they are stored as name-only, not in
name-value pairs), it may throw off directive matching for any bound attributes
that come after. This commit changes the directive matching logic to skip
classes altogether.
