Remove benches from `rustc_middle`
These benches benchmark rust langauge features and not the compiler, so they seem to be in the wrong place here. They also all take <1ns, making them pretty useless. Looking at their git history, they just seem to have been carried around for many, many years. This commit ends their journey.
Neither require nor imply lifetime bounds on opaque type for well formedness
The actual hidden type can live arbitrarily longer than any individual lifetime and arbitrarily shorter than all but one of the lifetimes.

This is a **breaking change** but it is a necessary soundness fix

fix a ui test
use `into`
fix clippy ui test
fix a run-make-fulldeps test
implement `IntoQueryParam<DefId>` for `OwnerId`
use `OwnerId` for more queries
change the type of `ParentOwnerIterator::Item` to `(OwnerId, OwnerNode)`
Always print '_, even for erased lifetimes.
Explicit lifetime arguments are now the recommended syntax in rust 2018 and rust 2021. This PR applies this discipline to rustc itself.
Introduce mir::Unevaluated
Previously the distinction between unevaluated constants in the type-system and in mir was not explicit and a little confusing. Probably better to introduce its own type for that.

Note if mismatched types have a similar name
If users get a type error between similarly named types, it will point out that these are actually different types, and where they were defined.
Const unification is already infallible, remove the error handling logic
r? `@lcnr`
is this expected to be used in the future? Right now it is dead code.
FIX - ambiguous Diagnostic link in docs
UPDATE - rename diagnostic_items to IntoDiagnostic and AddToDiagnostic
[Gardening] FIX - formatting via `x fmt`
FIX - rebase conflicts. NOTE: Confirm wheather or not we want to handle TargetDataLayoutErrorsWrapper this way
DELETE - unneeded allow attributes in Handler method
FIX - broken test
FIX - Rebase conflict
UPDATE - rename residual _SessionDiagnostic and fix LintDiag link
Improve error for when query is unsupported by crate
This is an improvement to the error message mentioned on #101666. It seems like a good idea to also add [this link to the rustc-dev-guide](https://rustc-dev-guide.rust-lang.org/query.html), if explaining the query system in detail is a concern here, but I'm unsure if there is any restrictions on adding links to error messages.
