[LLVM][utils] Add script which clears release notes (#153593) The script copies `ReleaseNotesTemplate.txt` to corresponding `ReleaseNotes.rst`/`.md` to clear release notes. The suffix of `ReleaseNotesTemplate.txt` must be `.txt`. If it is `.rst`/`.md`, it will be treated as a documentation source file when building documentation.
