bazel syntax: abolish Environment.StarlarkContext

The bulk of this change eliminates parameters of type
StarlarkContext in annotated methods, replacing them
by Environment parameters if not already present.
From the Environment, the BazelStarlarkContext can
be retrieved using getThreadLocal.

The only interesting parts are:

Environment: delete {get,set}StarlarkContext;
use {get,set}ThreadLocal instead.
Also, sprinkle 'private' keywords.

Label: store the HasRepoMapping as a thread-local.
Its value is an alias for the BazelStarlarkContext, but
we can't mention that type down here.

BazelStarlarkContext: define and use BSC.from(Environment),
which loads the Bazel info from a Starlark thread,
and BSC.storeInThread(Environment), which stores it,
plus the Label.RepoMapping, so we don't forget it.

ConfiguredRuleClassProvider: inline one flavor of
createSkylarkRuleClassEnvironment into the other.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
