Rollup merge of #64809 - davidtwco:issue-64768-target-feature-const, r=varkor 
hir: Disallow `target_feature` on constants

Fixes #64768.

This PR fixes an ICE when `#[target_feature]` is applied to constants by disallowing this with the same error as when `#[target_feature]` is applied to other places it shouldn't be.

I couldn't see anything in the [RFC](https://github.com/rust-lang/rfcs/blob/master/text/2045-target-feature.md) that suggested that `#[target_feature]` should be applicable to constants or any tests that suggested it should, though I might have missed something - if this is desirable in future, it remains possible to remove this error (but for the time being, I think this error is better than an ICE).

I also added some extra cases to the test for other places where `#[target_feature]` should not be permitted.
