release: cut the v10.0.0-rc.3 release

Libraries are still build using view engine even after Ivy being the default engine for building angular apps. Added note on why libraries are built using VE and how they will be automatically compiled in Ivy using ngcc making it compatible for both

Fixes #35625

PR Close #36556

-# fix(ngcc): ensure lockfile is removed when `analyzeFn` fails
-#
-# Previously an error thrown in the `analyzeFn` would cause the ngcc process to exit immediately
-# without removing the lockfile, and potentially before the unlocker process had been successfully
-# spawned resulting in the lockfile being orphaned and left behind.
-#
-# Now we catch these errors and remove the lockfile as needed.

-# feat(bazel): simplify ng_package by dropping esm5 and fesm5
-#
-# esm5 and fesm5 distributions are no longer needed and have been deprecated in the past.
-#
-# https://v9.angular.io/guide/deprecations#esm5-and-fesm5-code-formats-in-angular-npm-packages
-#
-# This commit modifies ng_package to no longer distribute these two formats in npm packages built by
-# ng_package (e.g. @angular/core).
-#
-# This commit intentionally doesn't fully clean up the ng_package rule to remove all traces of esm5
-# and fems5 build artifacts as that is a bigger cleanup and currently we are narrowing down the
-# scope of this change to the MVP needed for v10, which in this case is 'do not put esm5 and fesm5'
-# into the npm packages.
-#
-# More cleanup to follow: https://angular-team.atlassian.net/browse/FW-2143
-#
-# BREAKING CHANGE: esm5 and fesm5 format is no longer distributed in Angular's npm packages e.g.
-# @angular/core
-#
-# Angular CLI will automatically downlevel the code to es5 if differential loading is enabled in the
-# Angular project, so no action is required from Angular CLI users.
-#
-# If you are not using Angular CLI to build your application or library, and you need to be able to
-# build es5 artifacts, then you will need to downlevel the distributed Angular code to es5 on your
-# own.

 ## <a name="rules"></a> Coding Rules
 To ensure consistency throughout the source code, keep these rules in mind as you are working:
 
 * All features or bug fixes **must be tested** by one or more specs (unit-tests).
-* All public API methods **must be documented**.
-* We follow [Google's JavaScript Style Guide][js-style-guide], but wrap all code at **100 characters**.

+## <a name="commit"></a> Commit Message Guidelines
 
+We have very precise rules over how our git commit messages can be formatted.  This leads to **more
+readable messages** that are easy to follow when looking through the **project history**.  But also,
+we use the git commit messages to **generate the Angular change log**.
 
-## <a name="commit"></a> Commit Message Format
-
-*This specification is inspired and supersedes the [AngularJS commit message format][commit-message-format].*
-
-We have very precise rules over how our Git commit messages must be formatted.
-This format leads to **easier to read commit history**.
-
-Each commit message consists of a **header**, a **body**, and a **footer**.
-
+### Commit Message Format
+Each commit message consists of a **header**, a **body** and a **footer**.  The header has a special
+format that includes a **type**, a **scope** and a **subject**:
 
 ```
-<header>
+<type>(<scope>): <subject>
 <BLANK LINE>
 <body>
 <BLANK LINE>
 <footer>
 ```
 
-The `header` is mandatory and must conform to the [Commit Message Header](#commit-header) format.
+The **header** is mandatory and the **scope** of the header is optional.
 
-The `body` is mandatory for all commits except for those of scope "docs".
-When the body is required it must be at least 20 characters long.
+Any line of the commit message cannot be longer than 100 characters! This allows the message to be easier
+to read on GitHub as well as in various git tools.
 
-The `footer` is optional.
+The footer should contain a [closing reference to an issue](https://help.github.com/articles/closing-issues-via-commit-messages/) if any.
 
-Any line of the commit message cannot be longer than 100 characters.

-##### Summary
-
-Use the summary field to provide a succinct description of the change:
+### Subject
+The subject contains a succinct description of the change:
 
 * use the imperative, present tense: "change" not "changed" nor "changes"
 * don't capitalize the first letter
 * no dot (.) at the end
 
+### Body
+Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes".
+The body should include the motivation for the change and contrast this with previous behavior.
 
-#### Commit Message Body
+### Footer
+The footer should contain any information about **Breaking Changes** and is also the place to
+reference GitHub issues that this commit **Closes**.
 
-Just as in the summary, use the imperative, present tense: "fix" not "fixed" nor "fixes".
-
-Explain the motivation for the change in the commit message body. This commit message should explain _why_ you are making the change.
-You can include a comparison of the previous behavior with the new behavior in order to illustrate the impact of the change.
-
-
-#### Commit Message Footer
-
-The footer can contain information about breaking changes and is also the place to reference GitHub issues, Jira tickets, and other PRs that this commit closes or is related to.
-
-```
-BREAKING CHANGE: <breaking change summary>
-<BLANK LINE>
-<breaking change description + migration instructions>
-<BLANK LINE>
-<BLANK LINE>
-Fixes #<issue number>
-```
-
-Breaking Change section should start with the phrase "BREAKING CHANGE: " followed by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.
-
-
-### Revert commits
-
-If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit.
-
-The content of the commit message body should contain:
-
-- information about the SHA of the commit being reverted in the following format: `This reverts commit <SHA>`,
-- a clear description of the reason for reverting the commit message.
+**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. The rest of the commit message is then used for this.
 
+A detailed explanation can be found in this [document][commit-message-format].
