Downgrade priors version mismatch warning

[keith]

As a user when you're changing between versions of these files there's nothing you could do to avoid invalidation so this warning feel superfluous

[artemcm]

Could you please replace the warning with an incremental build remark, instead of removing it?
Something like:

reporter?.report("Will not do cross-module incremental builds, wrong version of priors; expected \(expected) but read \(read) at '\(dependencyGraphPath)'") 

[keith]

@swift-ci please test

Updated to use that option instead! FWIW I do think that even a remark (if the user sees that) might be a bit more noise that desired (related thread: https://forums.swift.org/t/incremental-compilation-has-been-disabled-it-is-not-compatible-with-whole-module-optimization/66092). Maybe there should be a --verbose mode that implies these instead?

The remarks are really only meant for all of us to debug what's going on with incremental builds, so I think a bit of verbosity of this kind is just fine. Still though, very good to move it away from being an actual warning.

Yea that makes sense, but I guess users do still end up seeing these, which might be confusing especially for ones that are this low level
