Now that the Angular LS is a proper tsserver plugin, it does not make
sense for it to maintain its own language service API.
This is part one of the effort to remove our custom LanguageService
interface.
This interface is cumbersome because we have to do two transformations:
ng def -> ts def -> lsp definition
The TS LS interface is more comprehensive, so this allows the Angular LS
to return more information.

Publishing of NGCC packages should not be allowed. It is easy for a user to publish an NGCC'd version of a library they have workspace libraries which are being used in a workspace application.
If a users builds a library and afterwards the application, the library will be transformed with NGCC and since NGCC taints the distributed files that should be published.
With this change we use the npm/yarn `prepublishOnly` hook to display and error and abort the process with a non zero error code when a user tries to publish an NGCC version of the package.

Previously, when run with `createNewEntryPointFormats: true`, `ngcc`
would only update `package.json` with the new entry-point for the first
format property that mapped to a format-path. Subsequent properties
mapping to the same format-path would be detected as processed and not
have their new entry-point format recorded in `package.json`.
This commit fixes this by ensuring `package.json` is updated for all
matching format properties, when writing an `EntryPointBundle`.
PR Close#32052
Remove the `formatProperty` property from the `EntryPointBundle`
interface, because the property is not directly related to that type.
It was only used in one place, when calling `fileWriter.writeBundle()`,
but we can pass `formatProperty` directrly to `writeBundle()`.

This refactoring more clearly separates the different phases of the work
performed by `ngcc`, setting the ground for being able to run each phase
independently in the future and improve performance via parallelization.

This change basically moves some checks to happen up front and ensures
we don't try to process any more properties than we absolutely need.
(The properties would not be processed before either, but we would
consider them, before finding out that they have already been processed
or that they do not exist in the entry-point's `package.json`.)
This change should make no difference in the work done by `ngcc`, but it
transforms the code in a way that makes the actual work known earlier,
thus making it easier to parallelize the processing of each property in
the future.

In commit 7b55ba58b (part of PR #29092), the implementation of
`makeEntryPointBundle()` was changed such that it now always return
`EntryPointBundle` (and not `null`).
However, the return type was not updated and as result we continued to
unnecessarily handle `null` as a potential return value in some places.
This commit fixes the return type to reflect the implementation and
removes the redundant code that was dealing with `null`.

ngcc analyzes the dependency structure of the entrypoints it needs to
process, as the compilation of entrypoints is ordering sensitive: any
dependent upon entrypoint must be compiled before its dependees. As part
of the analysis of the dependency graph, it is detected when a
dependency of entrypoint is not installed, in which case that entrypoint
will be marked as ignored.
For libraries that work with Angular Universal to run in NodeJS, imports
into builtin NodeJS modules can be present. ngcc's dependency analyzer
can only resolve imports within the TypeScript compilation, which
builtin modules are not part of. Therefore, such imports would
erroneously cause the entrypoint to become ignored.
This commit fixes the problem by taking the NodeJS builtins into account
when dealing with missing imports.

ngcc analyzes the dependency structure of the entrypoints it needs to

When a target entrypoint to compile is provided, it could occur that
given target is considered ignored because one of its dependencies might
be missing. This situation was not dealt with currently, instead
resulting in a crash of ngcc.
This commit prevents the crash by taking the above scenario into account.

Previously, `ngcc` would avoid processing a `formatPath` that a property
in `package.json` mapped to, if either the _property_ was marked as
processed or the `formatPath` (i.e. the file(s)) was processed in the
same `ngcc` run (since the `compiledFormats` set was not persisted
across runs).
This could lead in a situation where a `formatPath` would be compiled
twice (if for example properties `a` and `b` both mapped to the same
`formatPath` and one would run `ngcc` for property `a` and then `b`).
This commit fixes it by ensuring that as soon as a `formatPath` has been
processed all corresponding properties are marked as processed (which
persists across `ngcc` runs).
PR Close#32003
Previously, when `ngcc` was called with `compileAllFormats === false`
(i.e. how `@angular/cli` calls it), it would not attempt to process
more properties, once the first was successfully processed. However, it
_would_ continue looping over them and perform some unnecessary
operations, such as:
- Determining the format each property maps to (which can be an
expensive operation for some properties mapping to either UMD or
CommonJS).
- Checking whether each property has been processed (which involves
checking whether any property has been processed with a different
version of `ngcc` each time).
- Potentially marking properties as processed (which involves a
file-write operation).
This commit avoids the unnecessary operations by entirely skipping
subsequent properties, once the first one has been successfully
processed. While this theoretically improves performance, it is not
expected to have any noticeable impact in practice, since the list of
`propertiesToConsider` is typically small and the most expensive
operation (marking a property as processed) has low likelihood of
happening (plus these operations are a tiny fraction of `ngcc`'s work).
PR Close#32003
Previously, when `ngcc` needed to mark multiple properties as processed
(e.g. a processed format property and `typings` or all supported
properties for a non-Angular entry-point), it would update each one
separately and write the file to disk multiple times.
This commit changes this, so that multiple properties can be updated at
once with one file-write operation. While this theoretically improves
performance (reducing the I/O operations), it is not expected to have
any noticeable impact in practice, since these operations are a tiny
fraction of `ngcc`'s work.
This change will be useful for a subsequent change to mark all
properties that map to the same `formatPath` as processed, once it is
processed the first time.

This PR changes the language service to work in two different modes:
1. TS + Angular
Plugin augments TS language service to provide additonal Angular
information. This only works with inline template and is meant to be
used as a local plugin (configured via tsconfig.json).
2. Angular only
Plugin only provides information on Angular templates, no TS info at
all. This effectively disables native TS features and is meant for
internal use only.
Default mode is `angularOnly = false` so that we don't break any users
already using Angular LS as local plugin.
As part of the refactoring, `undefined` is removed from type aliases
because it is considered bad practice.
go/tsstyle#nullableundefined-type-aliases
```
Type aliases must not include |null or |undefined in a union type.
Nullable aliases typically indicate that null values are being passed
around through too many layers of an application, and this clouds the
source of the original issue that resulted in null. They also make it
unclear when specific values on a class or interface might be absent.

Fixes Ivy's directive matching not capturing attribute selectors when there is one class binding, one style binding and a regular binding that precede the attribute that would match the directive. The issue appears to come from the fact that we weren't skipping over style bindings correctly which was throwing the loop off not to go into `bindingsMode` and to skip some of the bindings when matching.

This commit changes the emit order of ngcc when a class has multiple static
fields being assigned. Previously, ngcc would emit each static field
followed immediately by any extra statements specified for that field. This
causes issues with downstream tooling such as build optimizer, which expects
all of the static fields for a class to be grouped together. ngtsc already
groups static fields and additional statements. This commit changes ngcc's
ordering to match.

Prior to this commit, the `schemas` configuration was applied to top-level view only.

AngularJS compilation is a synchronous operation (unless having to fetch
a template, which is not supported for downgraded components).
Previously, ngUpgrade tried to retain the synchronous nature of the
compilation for downgraded components (when possible), by using a
synchronous thenable implementation (`ParentInjectorPromise`). This was
accidentally broken in #27217 by replacing a call to
`ParentInjectorPromise#then()` (which can be synchronous) with a call to
`Promise.all()` (which is asynchronous).
This commit fixes this by introducing a `SyncPromise.all()` static
method; similar to `Promise.all()` but retaining the synchronous
capabilities of `SyncPromise` (which `ParentInjectorPromise` inherits
from).

If a project being built with ngtsc has no templates to check, then ngtsc
previously generated an empty typecheck file. This seems to trigger some
pathological behavior in TS where the entire user program is re-checked,
which is extremely expensive. This likely has to do with the fact that the
empty file is not considered an ES module, meaning the module structure of
the program has changed.
This commit causes an export to be produced in the typecheck file regardless
of its other contents, which guarantees that it will be an ES module. The
pathological behavior is avoided and template type-checking is fast once
again.
