clang: add helper script to keep package updated
We'll need to update our clang when Msys2 updates theirs and reapply our customisations every time, so a script makes this job less tedious and leaves no room to miss a step of the process. This script performs the same steps as the previous two commits. (it was used to generate the files for those) Signed-off-by: Matthias Aßhauer <[email protected]>
