Allow rules and targets to specify extra execution platform constraints.

RuleClass.Builder now allows authors to specify whether a rule's targets
can add additional constraints on the execution platform, and to declare
additional constraints for all targets of that rule.

Targets which support this now have an attribute,
"exec_compatible_with", which supports specifying additional constraints
that the execution platform used must match.

This attribute is non-configurable. It will only affect execution
platforms used during toolchain resolution.

Part of #5217.

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.
