Improve MSVC Crosstool

- Remove `/D_SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS`: it disables warnings for deprecated C++ headers (`<stdext/*>`, `<hash_map>` etc.). Only useful for legacy codebase.
- Remove `/J`: `char` is signed according to ISO C++. There is no reason to make `char` unsigned by default.
- Remove default `/Gy`: moved to feature (`smaller_binary`).
- Remove default `/GF`: string pooling, enabled by default with `/O2`.
- Remove `/DDEBUG` in `dbg` mode: conflict with macros defined in some OSS projects such as LLVM. User should use standard `NDEBUG` to detect debug mode.

Implements a few general `feature` to abstract away details about the compiler:
- `treat_warnings_as_errors`: aka `-Werror`.
- `frame_pointer`: aka `-fno-omit-frame-pointer'.
- `determinism`: redact `__TIME__` macros etc.
- `disable_assertions`: allow user to have `assert/DCHECK` back even in `opt` mode.
- `smaller_binary`: common optimization enabled in `opt` mode. Still allow user to disable it in `opt` (such as when using ASAN).
- `ignore_noisy_warnings`: suppress a bunch of warnings most people don't care. If users want to be pedantic, they can still get those warnings back with `--features=-ignore_noisy_warnings`.

Closes #5519.

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.
