feat(update): Report when incompatible-rust-version packages are selected

### What does this PR try to resolve?

In discussin this in rust-lang#13873, it highlighted that we need to make sure we
tell people when incompatible-rust-version packages are selected.

I decided to keep "latest" and "required rust version" messages mutually
exclusive to avoid too much noise.  I gave "required rust version"
higher precedence as its the more critical to operation and, if you are
using an MSRV-incompatible package, it likely is "latest" already.

### How should we test and review this PR?

### Additional information

I was tempted to change colors to make "required rust version" stand out
from "latest" but was unsure what direction to go, so I held off.
Options included
- red for "required rust version", yellow for "latest"
- yellow for "required rust version", nothing for "latest"

There is also more discussion on how to format "latest" at rust-lang#13908.
