A previous commit implemented a streamlined performance metric reporting
system for the compiler-cli, controlled via the compiler option
`tracePerformance`.
This commit adds a custom Bazel flag rule //packages/compiler-cli:ng_perf
to the repository, and wires it through to the `ng_module` implementation
such that if the flag is set, `ng_module` will produce perf results as part
of the build. The underlying mechanism of `//:ng_perf` is not exported from
`@angular/bazel` as a public rule that consumers can use, so there is little
risk of accidental dependency on the contents of these perf traces.
An alias is added so that `--ng_perf` is a Bazel flag which works in our
repository.

Updates to rules_nodejs 2.2.0. This is the first major release in 7 months and includes a number of features as well
as breaking changes.
Release notes: https://github.com/bazelbuild/rules_nodejs/releases/tag/2.0.0
Features of note for angular/angular:
* stdout/stderr/exit code capture; this could be potentially be useful
* TypeScript (ts_project); a simpler tsc rule that ts_library that can be used in the repo where ts_library is too
heavy weight
Breaking changes of note for angular/angular:
* loading custom rules from npm packages: `ts_library` is no longer loaded from `@npm_bazel_typescript//:index.bzl`
(which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`
* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.
* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
`@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
`@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
internals for ng_module.
* runfiles.resolve will now throw instead of returning undefined to match behavior of node require
Other changes in angular/angular:
* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.
NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.
* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.

Disables Bazel runfile tree creation. Only if a given
execution strategy relies on runfile tree creation, the
runfile tree is created lazily. This helps as currently
Bazel spends unnecessary time on CI building runfile trees
for tests which are cached and aren't re-run.
The goal is to spend less time on CI for cached test/build
targets. We can't measure impact yet as there are targets
for the integration tests that hide the potential benefits.
on the components repo a 80% time reduction could be observed.

* it's tricky to get out of the runfiles tree with `bazel test` as `BUILD_WORKSPACE_DIRECTORY` is not set but I employed a trick to read the `DO_NOT_BUILD_HERE` file that is one level up from `execroot` and that contains the workspace directory. This is experimental and if `bazel test //:test.debug` fails than `bazel run` is still guaranteed to work as `BUILD_WORKSPACE_DIRECTORY` will be set in that context
* test //integration:bazel_test and //integration:bazel-schematics_test exclusively
* run "exclusive" and "manual" bazel-in-bazel integration tests in their own CI job as they take 8m+ to execute
```
//integration:bazel-schematics_test PASSED in 317.2s
//integration:bazel_test PASSED in 167.8s
```
* Skip all integration tests that are now handled by angular_integration_test except the tests that are tracked for payload size; these are:
- cli-hello-world*
- hello_world__closure
* add & pin @babel deps as newer versions of babel break //packages/localize/src/tools/test:test
@babel/core dep had to be pinned to 7.6.4 or else //packages/localize/src/tools/test:test failed. Also //packages/localize uses @babel/generator, @babel/template, @babel/traverse & @babel/types so these deps were added to package.json as they were not being hoisted anymore from @babel/core transitive.
NB: integration/hello_world__systemjs_umd test must run with systemjs 0.20.0
NB: systemjs must be at 0.18.10 for legacy saucelabs job to pass
NB: With Bazel 2.0, the glob for the files to test `"integration/bazel/**"` is empty if integation/bazel is in .bazelignore. This glob worked under these conditions with 1.1.0. I did not bother testing with 1.2.x as not having integration/bazel in .bazelignore is correct.

Now that all compile decisions are determined by the define=angular_ivy_enabled
flag, we can remove the setting of the define=compile flag throughout the repo.
PR Close#33983
Beginning of migration away from --define=compile=* to --define=angular_ivy_enabled=*.
Additionally, to make it clearer to developers, we will encourage use of --config=ivy
instead of directy setting the --define flag, this abstraction will allow us more
flexibility as we move foward with relation to our compile decisions at build time.

We have determined that the upload time cost of remote caching via http is too costly
to be effective for our distributed usage scenario. However this cost is still worth
it for us for Windows CI runs on a full cache hit move from a ~60 minute task to ~10
minutes.
It is worth noting that this remote http-caching is entirely separate from RBE caching
mechanisms.

Also removes `build:remote --spawn_strategy=remote` from .bazelrc. It seems that with Bazel 1.0.0 setting `--incompatible_list_based_execution_strategy_selection=false` no longer works around the issue with npm_package that it did when it was added. The error that was originally observed has returned after updating to Bazel 1.0.0:
```
ERROR: /home/circleci/ng/packages/angular_devkit/build_optimizer/BUILD:66:1: Assembling npm package packages/angular_devkit/build_optimizer/npm_package failed: No usable spawn strategy found for spawn with mnemonic Action.

```
This commit removes both `—incompatible_list_based_execution_strategy_selection=false` as well as `build:remote --spawn_strategy=remote` which means that Bazel will do the default behavior of picking the first available strategy from the default list, which is `remote,worker,sandboxed,local`. See https://github.com/bazelbuild/bazel/issues/7480 for more details.
Not updating to Bazel 1.1.0 yet due to a docker permissions CI issue that was observed on the angular repo that is unresolved. See https://github.com/angular/angular/pull/33367#issuecomment-547643246.

After eb00a37eb8 we accidentally regressed due to some
recent changes where more flags were added at the end of the bazelrc. This means that all
flags which were added after the `try-import` can no longer be overwritten easily in the
user project bazelrc file. Technically developers can always overwrite flags though the
command line, but it's a productivity blocker if developers can't permanently overwrite these
flags through the user config
