Auto merge of #54997 - davidtwco:issue-54896, r=nagisa

The #[panic_handler] attribute can be applied to non-functions

Fixes #54896.

This commit extends the existing lang items functionality to assert
that the `#[lang_item]` attribute is only found on the appropriate item
for any given lang item. That is, language items representing traits
must only ever have their corresponding attribute placed on a trait, for
example.
