refactor(compiler-cli): add script to update all golden partial files (…

…angular#39989)

The golden files for the partial compliance tests need to be updated
with individual Bazel run invocations, which is not very ergonomic when
a large number of golden files need to updated. This commit adds a
script to query the Bazel targets that update the goldens and then runs
those targets sequentially.
