To make our test output i.e. devmode output more aligned
with what we produce in the NPM packages, or to be more
aligned with what Angular applications will usually consume,
the devmode output is switched from ES5 to ES2015.
Additionally various tsconfigs (outside of Bazel) have been
updated to match with the other parts of the build. The rules
are:
ES2015 for test configurations, ES2020 for actual code that will
end up being shipped (this includes the IDE-only tsconfigs).

This wires up the `@angular/localize/tools` entry-point. For context:
This entry-point is being created to avoid deep imports into
`@angular/localize/src/tools/<..>` like the CLI relies on. Deep imports
do not play well with strict ESM, and now that all APF packages are
strict ESM, the tool code needs to be either strict ESM as well.
We use ESBuild to create individual bundles for the CLI entry-points,
and the actual tool entry-point. We use a bundler because this enables
the localize code be ESM compatible. Without a bundler, all relative imports
within the `tools` entry-point would need to explicitly have the `.js`
extension. This would be cumbersome and hard to maintain/enforce or
validate.
One might wonder why this is not a standard APF entry-point then. The
answer is that the APF entry-points do not support exposing the CLI
binaries (like `yarn localize-translate`). This could be done through
tertiary entry-points, but using ESBuild directly gives us more control
for now. We might want to revisit this in the future again.

Moves the `src/tools` folder of the `@angular/localize` package into the
top-level of the package. This is in preparation of actually exposing an
entry-point for the tools that can be accessed using
`@angular/localize/tools`.
We want to expose such an entry-point because the CLI currently
deep-imports into various places of the tools, but this will not
work well with strict ESM because the localize tool depends on the
v13 strict ESM packages like the `@angular/compiler` or
`@angular/compiler-cli`.
