Summarize platform story for Bazel 1.0

In fulfillment of https://docs.google.com/document/d/1ml_t5vUqFH7HR4c2j2bT3sApdBT5A0TQ31E7R511dnY/edit?pli=1#heading=h.5mcn15i0e1ch.

This doesn't cover everything mentioned in the doc. In particular:

1. I shied away from mentioning migration timelines since I don't think there are clear ones to communicate now
1. Likewise I avoided promising precisely which version of Bazel has which feature.
1. Also didn't discuss the nuances of platforms vs. constriants vs. build_settings vs. toolchain properties and the right combination of them to design clear and sensible builds. I *think* that's a big enough topic to be its own doc.

But hopefully this offers at least a reasonable initial orientation.

Closes #9446.

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.
