Test Plan

I took test cases from esbuild https://github.com/evanw/esbuild/pull/2102, the original test case of Typescript pull request related to semantics, which we don't care too much about. esbuild Optional variance annotations pull request test case is more suitable for us.

This pull request is pretty big, so I prefer to separate the optional variance annotation formatting another pr
