* contracts-bedrock: OptimismPortal reduce codesize

Reduce the codesize of the OptimismPortal and the OptimismPortal2
by converting `require` statements into custom error reverts.
Also remove legacy getters, they only bloat codesize.

This will help to reduce the diff of when we go to production
with custom gas token as that feature put the contract over the
codesize limit.
