Auto merge of #12381 - epage:msrv, r=weihanglo

fix: Set MSRV for internal packages

### What does this PR try to resolve?

Correctly communicates the MSRV we support to our users.

For packages that are more generally mean to be used by other people, I've punted on for now (see ehuss' comment on this PR).  We'll likely need to figure this out for #12432 though

### Additional information

This is prep for a future change which will have us use a fixed rust version for the semver tests with a PR updating them.
