Minor: Remove unnecessary canonicalize_name calls and validate via NormalizedName type

[notatallshaw]

This is a small follow up to #13581, the name attribute of the Wheel model class is now guaranteed to be canonicalized, this means there are many places where it is now redundant to call canonicalize_name.

To validate this is always true I have set some parameters to use the NormalizedName type from packaging, which is the type of the canonicalized name. I tried to keep this fairly minimal, there were many more places where a canonicalized name is always being used but changing the type on all of them started to make this PR a lot bigger than it needed to be.

We could also use the Version type for the version attribute instead of a str in the Wheel model, which would save a couple of calls to Version elsewhere, but this ended up being non-trivial in the LinkEvaluator.evaluate_link method, so I left it a more brave PR than this one.

Thanks for doing this! FWIW, this makes some small progress towards #7974.

Interesting, thanks for the info, I'll consider making a follow up PR that more thoroughly minimizes the use of canonicalize_name and maximize using NormalizedName type. But this PR was just meant to be a small follow up from #13581.
