70810a36 - turn on -Wall with a few exceptions in Bazel build

turn on -Wall with a few exceptions in Bazel build Summary: We add the following exceptions: * sign-compare: this is heavily violated in our codebase * unknown-pragmas: we use this intentionally for some loop unrolling in CUDA Because they are included in -Wall by default, we remove the following warnings from our explicit list: * unused-function * unused-variable Test Plan: Rely on CI.
