Auto merge of #107421 - cjgillot:drop-tracking-mir, r=oli-obk
Enable -Zdrop-tracking-mir by default

This PR enables the `drop-tracking-mir` flag by default. This flag was initially implemented in https://github.com/rust-lang/rust/pull/101692.

This flag computes auto-traits on generators based on their analysis MIR, instead of trying to compute on the HIR body. This removes the need for HIR-based drop-tracking, as we can now reuse the same code to compute generator witness types and to compute generator interior fields.
