Update DEFAULT_MACOS_CPU to match host

With Apple Silicon machines host tools that use the apple_binary, or
apple fragment to fetch the CPU would be built for the wrong
architecture, even though the C++ logic would correctly identify the
host CPU. This changes this hardcoded value to correctly determine Apple
Silicon as arm64, and otherwise fallback to x86_64.

Fixes https://github.com/bazelbuild/bazel/issues/12671

Closes #13440.

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.
