bazel: fix lef/lib/gds globs and cva6 include path

- Use specific file extensions in lef/lib/gds BUILD files to prevent
  BUILD.bazel from being picked up as a liberty/gds file
- Remove common_cells/include/common_cells package boundary so parent
  include filegroup can glob recursively into subdirectories
- Add allow_empty to gds globs (only .gds.gz files exist)
