[mypyc] Group related tests together in separate test files (#9130)

This primarily splits the big run.test file into several smaller files and renames that
file to run-misc.test.

In the future, I hope that most new test cases will be added outside the misc file.

I haven't changed the test cases, and I've verified that the total number of test cases
remains the same.
