Add flag for whether patches should be committed

[jmazanec15]

Description

Related to #1651. This change adds a flag to gradle and cmake for whether patches should be committed to the native libs. Committing the changes prevents the build from repeating itself everytime cmake is run, but it requires user config for git on the host environment. non-dev environments (i.e. artifact build envs) typically do not have user configured and lead to failures like:

@jmazanec15 just to note you can remove the dco.yml in .github/workflows as it has already been replaced by the dco app.
