[bazel] Clean up unused exported files (llvm#114620)

Some minor cleanup to the bazel files. These exported files are not
being referenced anymore in the tree, afaict, so let's clean them up.
Additionally, moved one of the filegroup targets higher to be consistent
with other filegroup usages where it's defined before first usage.
