This is another PR towards the goal of getting Z3 to compile cleanly when included via FetchContents into clang-tidy, which uses a pretty strict set of warnings. This is a second version of https://github.com/Z3Prover/z3/pull/9957. I address @NikolajBjorner 's comments about not changing the semicolons after macro invocations, because some editors work better with them present. It now, to the best of my ability, only deletes semis: * after the closing brace of namespace decl. * after the closing brace of an extern "C" decl. * after a function definition. This PR is very large, but it consists entirely of deletions of semicolons in these situations. (If there was a way to update the previous PR, which had been closed, and that is preferable, please let me know. I couldn't figure it out.)
