build: add formatting targets for c and lua files (#19488)
The targets will only format files that have been changed in current
branch compared to the master branch. This includes unstaged, staged and
committed files.

Add following make and cmake targets:
formatc   - format changed c files
formatlua - format changed lua files
format    - run formatc and formatlua

Remove scripts/uncrustify.sh as this deprecates it.
