Basically all tests pass now, so we can count this as done until 3.7.0 final is out |

Fixes #4609 and #4733
Apart from just bumping the Scala version, this PR overhauls the Mill codegen to take advantage of scala/improvement-proposals#100. This lets us remove a whole bunch of hacks we were previously using to avoid needing the
.packageprefix: alias imports, exports, codegen renames, etc. which are now all unnecessary.All the codegen-related example tests in
./mill 'example.large.multi[_].local.server'pass, so it seems to work. Only hitting some issues with the-experimentalflag stopping us from rolling this out more broadlyUpstream issues
