This commit adds a method `overrideInlineTemplate` to the

in a Component without changing the TypeScript parts. This methods works
in a similar way as `MockTypescriptHost.override()`, which is used for
overriding external template.

This function needs to deduplicate the paths that are found from the
paths mappings. Previously this deduplication was not linear and also
called the expensive `relative()` function many times.
This commit, suggested by @JoostK, reduces the complexity of the deduplication
by using a tree structure built from the segments of each path.

Previously the `basePaths` were computed when the finder was instantiated.
This was a waste of effort in the case that the targeted entry-point is already
processed.
This change makes the computation of `basePaths` lazy, so that the work is
only done if they are actually needed.

In TS 3.9 the compiler will start to wrap ES2015 classes in an IIFE to help with
tree-shaking when the class has "associated" statements.
E.g.
```ts
let PlatformLocation = /** @class */ (() => {
...
class PlatformLocation {
}
...
return PlatformLocation;
})();
```

Only refresh transplanted views at the insertion location in Ivy.
Previously, Ivy would check transplanted views at both the insertion and
declaration points. This is achieved by adding a marker to the insertion
tree when we encounter a transplanted view that needs to be refreshed at
its declaration. We use this marker as an extra indication that we still
need to descend and refresh those transplanted views at their insertion
locations even if the insertion view and/or its parents are not dirty.
This change fixes several issues:
* Transplanted views refreshed twice if both insertion and declaration
are dirty. This could be an error if the insertion component changes
result in data not being available to the transplanted view because it
is slated to be removed.
* CheckAlways transplanted views not refreshed if shielded by
non-dirty OnPush (fixes#35400)
* Transplanted views still refreshed when insertion tree is detached
(fixes#21324)

Now that `ngcc/src/ngcc_options` imports `FileWriter` type, there is a
circular dependency detected by the `ts-circular-deps:check` lint check:
```
ngcc/src/ngcc_options.ts
→ ngcc/src/writing/file_writer.ts
→ ngcc/src/packages/entry_point_bundle.ts
→ ngcc/src/ngcc_options.ts

This commit moves the `PathMappings` type (and related helpers) to a
separate file to avoid the circular dependency.

The circular dependency was only with taking types into account. There
was no circular dependency for the actual (JS) code.

When running in parallel mode, worker processes forward errors thrown
during task processing to the master process, which in turn exits with
an error.
However, there are cases where the error is not directly related to
processing the entry-point. One such case is when there is not enough
memory (for example, due to all the other tasks being processed
simultaneously).
Previously, an `ENOMEM` error thrown on a worker process would propagate
to the master process, eventually causing ngcc to exit with an error.
Example failure: https://circleci.com/gh/angular/angular/682198
This commit improves handling of these low-memory situations by
detecting `ENOMEM` errors and killing the worker process, thus allowing
the master process to decide how to handle that. The master process will
put the task back into the tasks queue and continue processing tasks
with the rest of the worker processes (and thus with lower memory
pressure).
PR Close#36626
Previously, when the last worker process crashed, the master process
would try to re-spawn it indefinitely. This could lead to an infinite
loop (if for some reason the worker process kept crashing).
This commit avoids this by limiting the number of re-spawn attempts to
3, after which ngcc will exit with an error.
PR Close#36626
Previously, when running in parallel mode and a worker process crashed
while processing a task, it was not possible for ngcc to continue
without risking ending up with a corrupted entry-point and therefore it
exited with an error. This, for example, could happen when a worker
process received a `SIGKILL` signal, which was frequently observed in CI
environments. This was probably the result of Docker killing processes
due to increased memory pressure.
One factor that amplifies the problem under Docker (which is often used
in CI) is that it is not possible to distinguish between the available
CPU cores on the host machine and the ones made available to Docker
containers, thus resulting in ngcc spawning too many worker processes.
This commit addresses these issues in the following ways:
1. We take advantage of the fact that files are written to disk only
after an entry-point has been fully analyzed/compiled. The master
process can now determine whether a worker process has not yet
started writing files to disk (even if it was in the middle of
processing a task) and just put the task back into the tasks queue if
the worker process crashes.
2. The master process keeps track of the transformed files that a worker
process will attempt to write to disk. If the worker process crashes
while writing files, the master process can revert any changes and
put the task back into the tasks queue (without risking corruption).
3. When a worker process crashes while processing a task (which can be a
result of increased memory pressure or too many worker processes),
the master process will not try to re-spawn it. This way the number
or worker processes is gradually adjusted to a level that can be
accomodated by the system's resources.
Examples of ngcc being able to recover after a worker process crashed:
- While idling: https://circleci.com/gh/angular/angular/682197
- While compiling: https://circleci.com/gh/angular/angular/682209
- While writing files: https://circleci.com/gh/angular/angular/682267

Previously, ngcc would run in parallel mode (using the
`ClusterExecutor`) when there were at least 2 CPU cores (and all other
requirements where met). On systems with just 2 CPU cores, this meant
there would only be one worker process (since one CPU core is always
reserved for the master process). In these cases, the tasks would still
be processed serially (on the one worker process), but we would also pay
the overhead of communicating between the master and worker processes.
This commit fixes this by only running in parallel mode if there are
more than 2 CPU cores (i.e. at least 2 worker processes).

An enum declaration in TypeScript code will be emitted into JavaScript
as a regular variable declaration, with the enum members being declared
inside an IIFE. For ngcc to support interpreting such variable
declarations as enum declarations with its members, ngcc needs to
recognize the enum declaration emit structure and extract all member
from the statements in the IIFE.
This commit extends the `ConcreteDeclaration` structure in the
`ReflectionHost` abstraction to be able to capture the enum members
on a variable declaration, as a substitute for the original
`ts.EnumDeclaration` as it existed in TypeScript code. The static
interpreter has been extended to handle the extracted enum members
as it would have done for `ts.EnumDeclaration`.
