Ed Page 0d29d3f71b fix(resolver): Prefer MSRV, rather than ignore incompatible
This is another experiment for #9930.

Comparing preferring over exclusively using MSRV compatible:

Benefits
- Better error messages
- `--ignore-rust-version` is implicitly sticky

Downsides
- Can't backtrack for MSRV compatible version
- Still requires workspace-wide MSRV (compared to our desired end state of declaring MSRV as yet another dependency)

This builds on #12930
