compatibility_matrices: Add script to create the next.
Add a `bump.py` script that does the following:
- Create a commit in kernel/configs with the new versions
- Copy the latest compatibility matrix to a new compatibility matrix
- Fix Android.bp and Android.mk
Prerequisite:
- libvintf/Level.h must contain the mapping for the next release.
Test: bump.py 9 10
Bug: 279809082
