Currently, there's no supported way to invoke hdrgen tool from Bazel build. In order to support generating headers in Bazel build we need to:
- [ ] Add integration with [pyyaml](https://github.com/yaml/pyyaml) to Bazel build. Otherwise, Bazel-build libc:hdrgen py_binary can't run, since it fails in "import yaml" statement.
- [ ] Add `libc_generated_header` macro to wrap genrule that would invoke hdrgen tool to generate public libc header from YAML file.
- [ ] Use `libc_generated_header` for some of the common headers important for downstream users.
- [ ] Add support for running header tests: libc/test/include has a lot of unit tests, which are not ported to Bazel currently.
- [ ] (optional) add a convenient way to group generated headers, expose them together, and let llvm-libc users depend on them, similar to how `libc_release_library` is used to expose a subset of llvm-libc functions.
