When ngtsc compiles @angular/core, it rewrites core imports to the
r3_symbols.ts file that exposes all internal symbols under their
external name. When creating the FESM bundle, the r3_symbols.ts file
causes the external symbol names to be rewritten to their internal name.
Under ngcc compilations of FESM bundles, the indirection of
r3_symbols.ts is no longer in place such that the external names are
retained in the bundle. Previously, the external name `ɵdefineNgModule`
was explicitly declared internally to resolve this issue, but the
recently added `setClassMetadata` was not declared as such, causing
runtime errors.
Instead of relying on the r3_symbols.ts file to perform the rewrite of
the external modules to their internal variants, the translation is
moved into the `ImportManager` during the compilation itself. This
avoids the need for providing the external name manually.

Some engineers were already on Yarn 0.10.x which was permitted by the range in our package.json#engines
However this introduced 'integrity sha512' lines into the yarn.lock files.
Then when engineers use yarn 0.9 (in particular, Bazel did this) then the lock files get tons of meaningless edits.
We could force everyone back to yarn 0.9 but this commit chooses to instead advance everyone past 0.10

This integration test was created from a vanilla CLI generated
project with the following modifications:
* remove `PercentPipe` usage from `app.component.html`
- these are not yet supported by ivy
* changed `ng test` in `package.json` to only to `ng build`
- right now we can only confirm that the app will build
* hard-code `ngDevMode` in `index.html`
- the CLI does not yet set this correctly
PR Close#26403
* rename test helper script
* add material to the ngcc integration test
* add MatButton to ngcc integration test checks
* remove platform-server from ngcc integration test
This package does not yet compile as it contains a package-private
(internal) decorated class, which the ngcc compiler does not yet
handle.

* No longer depends on a custom CircleCI docker image that comes with Bazel pre-installed. Since Bazel is now available through NPM, we should be able to use the version from `@bazel/bazel` in order to enforce a consistent environment on CI and locally.
* This also reduces the amount of packages that need to be published (ngcontainer is removed)

Originally, the ivy_switch mechanism used Bazel genrules to conditionally
compile one TS file or another depending on whether ngc or ngtsc was the
selected compiler. This was done because we wanted to avoid importing
certain modules (and thus pulling them into the build) if Ivy was on or
off. This mechanism had a major drawback: ivy_switch became a bottleneck
in the import graph, as it both imports from many places in the codebase
and is imported by many modules in the codebase. This frequently resulted
in cyclic imports which caused issues both with TS and Closure compilation.
It turns out ngcc needs both code paths in the bundle to perform the switch
during its operation anyway, so import switching was later abandoned. This
means that there's no real reason why the ivy_switch mechanism needed to
operate at the Bazel level, and for the ivy_switch file to be a bottleneck.
This commit removes the Bazel-level ivy_switch mechanism, and introduces
an additional TypeScript transform in ngtsc (and the pass-through tsc
compiler used for testing JIT) to perform the same operation that ngcc
does, and flip the switch during ngtsc compilation. This allows the
ivy_switch file to be removed, and the individual switches to be located
directly next to their consumers in the codebase, greatly mitigating the
circular import issues and making the mechanism much easier to use.
As part of this commit, the tag for marking switched variables was changed
from __PRE_NGCC__ to __PRE_R3__, since it's no longer just ngcc which
flips these tags. Most variables were renamed from R3_* to SWITCH_* as well,
since they're referenced mostly in render2 code.
Test strategy: existing test coverage is more than sufficient - if this
didn't work correctly it would break the hello world and todo apps.

This commit also removes the extra jasminewd2 typings, since the changes
have been merged in the official typings with
DefinitelyTyped/DefinitelyTyped#28957.

`ngcc` adds marker files to each folder that has been
compiled, containing the version of the ngcc used.
When compiling, it will ignore folders that contain these
marker files, as long as the version matches.

When using ViewEncapsulation.ShadowDom, Angular will not remove the child nodes of the DOM node a root Component is bootstrapped into. This enables developers building Angular Elements to use the `<slot>` element to do native content projection.

This commit adds an integration test for ngcc, which runs ngcc
against most @angular packages. It does not yet make any assertions
on the result.
