Allow native.existing_rule/s() with --incompatible_existing_rules_immutable_view to be encoded as json and passed as **kwargs

To do so, we make ExistingRuleView and ExistingRulesView implement Map. This
requires getting rid of NotRepresentableException in starlarkifyValue (see
discussion in #13829) so that the view object's accessors don't throw. And
that is, arguably, the correct thing to do: the distinction between returning
null for some non-representable attributes vs. throwing an exception for others
was entirely artificial.

This in turn implies a small change in behavior: now, `existing_rule(x).keys()`
will omit all attributes whose values cannot be represented in Starlark. (The
old behavior was to allow some such attributes, and throw an exception when
their value was accessed.)

Bazel

{Fast, Correct} - Choose two

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

  • Speed up your builds and tests: Bazel rebuilds only 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.
