Command to build: `bazel build :d8`

Caveats:
  - Needs clang
  - Only supports x64 on Linux
  - Bare V8: no Wasm and no ICU
  - Still needs GN to generate inspector files

Drive-by fix: The file name for WATCHLISTS in the OWNERS file rule was
wrong, so fixing that too so that it's possible to modify WATCHLISTS
without eng reviewers approval in the future.
