Pete Bacon Darwin a94bdc6793 refactor(ivy): ngcc - pass whole entry-point object to `makeEntryPointBundle()` (#30591)
This simplifies the interface somewhat but also allows us to make use of
other properties of the EntryPoint object in the future.

Pete Bacon Darwin 7c4c676413 feat(ivy): customize ngcc via configuration files (#30591)
There are scenarios where it is not possible for ngcc to guess the format
or configuration of an entry-point just from the files on disk.

Such scenarios include:

1) Unwanted entry-points: A spurious package.json makes ngcc think
there is an entry-point when there should not be one.

2) Deep-import entry-points: some packages allow deep-imports but do not
provide package.json files to indicate to ngcc that the imported path is
actually an entry-point to be processed.

3) Invalid/missing package.json properties: For example, an entry-point
that does not provide a valid property to a required format.

The configuration is provided by one or more `ngcc.config.js` files:

* If placed at the root of the project, this file can provide configuration
for named packages (and their entry-points) that have been npm installed
into the project.

* If published as part of a package, the file can provide configuration
for entry-points of the package.

The configured of a package at the project level will override any
configuration provided by the package itself.

Pete Bacon Darwin 7186f9c016 refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921)
To improve cross platform support, all file access (and path manipulation)
is now done through a well known interface (`FileSystem`).

For testing a number of `MockFileSystem` implementations are provided.
These provide an in-memory file-system which emulates operating systems
like OS/X, Unix and Windows.

The current file system is always available via the static method,
`FileSystem.getFileSystem()`. This is also used by a number of static
methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass
`FileSystem` objects around all the time. The result of this is that one
must be careful to ensure that the file-system has been initialized before
using any of these static methods. To prevent this happening accidentally
the current file system always starts out as an instance of `InvalidFileSystem`,
which will throw an error if any of its methods are called.

You can set the current file-system by calling `FileSystem.setFileSystem()`.
During testing you can call the helper function `initMockFileSystem(os)`
which takes a string name of the OS to emulate, and will also monkey-patch
aspects of the TypeScript library to ensure that TS is also using the
current file-system.

Finally there is the `NgtscCompilerHost` to be used for any TypeScript
compilation, which uses a given file-system.

All tests that interact with the file-system should be tested against each
of the mock file-systems. A series of helpers have been provided to support
such tests:

* `runInEachFileSystem()` - wrap your tests in this helper to run all the
wrapped tests in each of the mock file-systems.
* `addTestFilesToFileSystem()` - use this to add files and their contents
to the mock file system for testing.
* `loadTestFilesFromDisk()` - use this to load a mirror image of files on
disk into the in-memory mock file-system.
* `loadFakeCore()` - use this to load a fake version of `@angular/core`
into the mock file-system.

All ngcc and ngtsc source and tests now use this virtual file-system setup.

Pete Bacon Darwin 16d7dde2ad refactor(ivy): ngcc - implement abstract FileSystem (#29643)
This commit introduces a new interface, which abstracts access
to the underlying `FileSystem`. There is initially one concrete
implementation, `NodeJsFileSystem`, which is simply wrapping the
`fs` library of NodeJs.

Going forward, we can provide a `MockFileSystem` for test, which
should allow us to stop using `mock-fs` for most of the unit tests.
We could also implement a `CachedFileSystem` that may improve the
performance of ngcc.

Pete Bacon Darwin 6af9b8fb92 fix(ivy): ngcc - do not copy external files when writing bundles (#30085)
Only the JS files that are actually part of the entry-point
should be copied to the new entry-point folder in the
`NewEntryPointFileWriter`.

Previously some typings and external JS files were
being copied which was messing up the node_modules
structure.

JoostK 8cba4e1f6b fix(ivy): ngcc - do not copy declaration files into bundle clone (#30020)
Previously, all of a program's files would be copied into the __ivy_ngcc__
folder where ngcc then writes its modifications into. The set of source files
in a program however is much larger than the source files contained within
the entry-point of interest, so many more files were copied than necessary.
Even worse, it may occur that an unrelated file in the program would collide
with an already existing source file, resulting in incorrectly overwriting
a file with unrelated content. This behavior has actually been observed
with @angular/animations and @angular/platform-browser/animations, where
the former package would overwrite declaration files of the latter package.

This commit fixes the issue by only copying relevant source files when cloning
a bundle's content into __ivy_ngcc__.

Pete Bacon Darwin 64e5628897 feat(ivy): ngcc - support creating a new copy of the entry-point format (#29092)
This commit adds a `NewEntryPointFileWriter` that will be used in
webpack integration. Instead of overwriting files in-place, this `FileWriter`
will make a copy of the TS program files and write the transformed files
there. It also updates the package.json with new properties that can be
used to access the new entry-point format.
