Introduces a shared Bazel platform for remote execution builds
using Google cloud. Previously we used `bazel_toolchains` for
providing the platform w/ additional CPP and Java toolchains
`bazel_toolchains` no longer provides default toolchains with the
latest version, but provides a tool (linux and windows only) for
generating toolchain/platforms, which then need to be checked
into the repository. This is quite inconvenient and cumbersome
(especially with no macOS support), so we just provide our own
platform and CPP toolchain within `//dev-infra`. This is more
simple than all the effort we'd need to make the toolchain
generation tool work (while it would also increase the amount
of checked-in sources significantly; with more unused toolchains
for CPP or Java)

* Without this BUILD file we were seeing errors about the reference to
expand_template.bzl in ng_rollup_bundle.bzl because dev-infra/bazel
was not considered a package.

We recently added a new folder for common bazel utilities
to `dev-infra`. The `ng_rollup_bundle` rule relies on an
utility that is provided by this `bazel/` folder.
Unfortunately though it looks like this folder is currently
not included in the NPM package, so that the `ng_rollup_bundle`
rule does not work as expected. This commit fixes that by
including the bazel utilities in the NPM package.

Refactors the `ng_rollup_bundle` rule to a macro that relies on
the `@bazel/rollup` package. This means that the rule no longer
deals with custom ESM5 flavour output, but rather only builds
prodmode ES2015 output. This matches the common build output
in Angular projects, and optimizations done in CLI where
ES2015 is the default optimization input.
The motiviation for this change is:
* Not duplicating rollup Bazel rules. Instead leveraging the official
rollup rule.
* Not dealing with a third TS output flavor in Bazel.The ESM5 flavour has the
potential of slowing down local development (as it requires compilation replaying)
* Updating the rule to be aligned with current CLI optimizations.
This also _fixes_ a bug that surfaced in the old rollup bundle rule.
Code that is unused, is not removed properly. The new rule fixes this by
setting the `toplevel` flag. This instructs terser to remove unused
definitions at top-level. This matches the optimization applied in CLI
projects. Notably the CLI doesn't need this flag, as code is always
wrapped by Webpack. Hence, the unused code eliding runs by default.
