Auto merge of #114739 - lcnr:int-infer-impls, r=compiler-errors
remove builtin `Copy` and `Clone` impl for float and int infer
it's only change is whether `{integer}: Copy` is ambiguous, this has the following properties
- these goals get proven earlier, potentially resulting in slightly better perf
- it causes inconsistent behavior and ICE if there do not exist impls for all integers, causing issues when using `#[no_core]`
- it means `Clone` has user-facing differences from other traits from `core` with the new solver because it can potentially guide inference there
- it's just very sus™ to have a builtin impl which applies during type inference but not afterwards
