gn_utils: Export proto import_dirs for all targets

Right now proto import_dirs are only exported for source_set targets.

In a future commit, import_dirs will be used by zero targets as well.

This cl renames `metadata.import_dirs` to `metadata.proto_import_dirs`.
I haven't found a way in GN to set `metadata.import_dirs` on a target
that already has `import_dirs`.
