Remove structural match from `TypeId`

As per rust-lang/rust#99189 (comment).

> Removing the structural equality might make sense, but is a breaking change that'd require a libs-api FCP.

rust-lang/rust#99189 (comment)

> Landing this PR now (well, mainly the "remove structural equality" part) would unblock `const fn` `TypeId::of`, since we only postponed that because we were guaranteeing too much.
