Add flag to remove most Objective-C dbg and opt compiler flags

Currently, Bazel sticks some extra compiler flags in when you compile
Objective-C in dbg or opt mode. If these flags are going to be set, they should
really be set in a CROSSTOOL rather than in the Bazel core; unfortunately,
backward compatibility requirements mean they can’t simply be removed. Add a
Bazel flag, `--incompatible_avoid_hardcoded_objc_compilation_flags`, that will
prevent Bazel from passing hard-coded flags to the Objective-C compiler.

This reimplements commit 0bbe38176e15d891a4e4cab2d8425e292de6cc5f (which was
rolled back in commit d5084589f3a549e520ea5f37af29faafce3c5bcf) behind a flag.

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.
