Report marker diagnostics during parsing, rather than evaluation #9338

Summary

I want to move towards a more normalized marker representation within the marker tree, which means that the things we warn against will disappear by the time we get to evaluation. I think it makes more sense to show these warnings when we create the tree, rather than when we evaluate it.

Is that better? Then I have to assign and return the value

I forgot to comment that, but this one is an explicit import to make exporting and rewriting to https://github.com/konstin/pep508_rs/blob/d155787317425e8ab897beef55a947e8ef28f9d8/src/verbatim_url.rs#L12-L13 easier

## Summary

This PR introduces a set of parallel structs to `MarkerValueString`,
`MarkerValueExtra`, and `MarkerValueVersion` that remove various pieces
of information and representations that shouldn't be available in the
marker algebra. To start, I've _just_ removed the invalid extra
component from `MarkerValueExtra` -- there are no other changes to the
representation. So, throughout the marker algebra, we can't represent
and thus don't have to worry about clauses with invalid extras.

The subsequent changes I plan to make are:

1. Removing `python_version`, since we exclusively use
`python_version_full` in the algebra.
2. Removing the deprecated aliases, such that we re-map to the correct
marker value.
3. Consolidating `sys_platform` and `platform_release` (the original
motivation).
