Adds the ability to pass extra arguments to gomock
Which issues(s) does this PR fix?
Fixes #4065
Closes #4066
Other notes for review
I prefer #4066 but I'm filing this alternative PR in case the maintainers prefer to have each flag listed explicitly instead of passing arbitrary flags to mockgen_tool, especially considering some of these only work for a specific fork of mockgen (Uber's fork)
