Rollup merge of #134140 - compiler-errors:unsafe-binders-ast, r=oli-obk

Add AST support for unsafe binders

I'm splitting up #130514 into pieces. It's impossible for me to keep up with a huge PR like that. I'll land type system support for this next, probably w/o MIR lowering, which will come later.

r? `@oli-obk`
cc `@BoxyUwU` and `@lcnr` who also may want to look at this, though this PR doesn't do too much yet
