resolve: Rename some cstore methods to match queries and add comments
about costs associated with replacing them with query calls.
Supersedes https://github.com/rust-lang/rust/pull/108346.

Add `try_canonicalize` to `rustc_fs_util` and use it over `fs::canonicalize`
This adds `try_canonicalize` which tries to call `fs::canonicalize`, but falls back to `std::path::absolute` if it fails. Existing `canonicalize` calls are replaced with it. `fs::canonicalize` is not guaranteed to work on Windows.

rustc: Remove unused `Session` argument from some attribute functions
(One auxiliary test file containing one of these functions was unused, so I removed it instead of updating.)
Eagerly intern and check CrateNum/StableCrateId collisions
r? ``@cjgillot``
It seems better to check things ahead of time than checking them afterwards.
The [previous version](https://github.com/rust-lang/rust/pull/108390) was a bit nonsensical, so this addresses the feedback
The name of NativeLib will be presented
Fixes#109144
I was working on a quick fix, but found change the name from `Option<Symbol>` to `Symbol` make life a little bit easier.
Install projection from RPITIT to default trait method opaque correctly
1. For new lowering strategy `-Zlower-impl-trait-in-trait-to-assoc-ty`, install the correct default trait method projection predicates (RPITIT -> opaque). This makes default trait body tests pass!
2. Fix two WF-checking bugs -- first, we want to make sure that we're always looking for an opaque type in `check_return_position_impl_trait_in_trait_bounds`. That's because the RPITIT projections are normalized to opaques during wfcheck. Second, fix RPITIT's param-envs by not adding the projection predicates that we install on trait methods to make default RPITITs work -- I left a comment why.
3. Also, just a small drive-by for `rustc_on_unimplemented`. Not sure if it affects any tests, but can't hurt.

Use `unused_generic_params` from crate metadata
Due to the way that `separate_provide_extern` interacted with the implementation of `<ty::InstanceDef<'tcx> as Key>::query_crate_is_local`, we actually never hit the foreign provider for `unused_generic_params`.
Additionally, since the *local* provider of `unused_generic_params` calls `should_polymorphize`, which always returns false if the def-id is foreign, this means that we never actually polymorphize monomorphic instances originating from foreign crates.
We don't actually encode `unused_generic_params` for items where all generics are used, so I had to tweak the foreign provider to fall back to `ty::UnusedGenericParams::new_all_used()` to avoid more ICEs when the above bugs were fixed.
Ensure value is on the on-disk cache before returning from `ensure()`.
The current logic for `ensure()` a query just checks that the node is green in the dependency graph.
However, a lot of places use `ensure()` to prevent the query from being called later. This is the case before stealing a query result.
If the query is actually green but the value is not available in the on-disk cache, `ensure` would return, but a subsequent call to the full query would run the code, and attempt to read from a stolen value.
This PR conforms the query system to the usage by checking whether the queried value is loadable from disk before returning.
Sadly, I can't manage to craft a proper test...
Should fix all instances of "attempted to read from stolen value".

Give proper error message when tcx wasn't passed to decoder
I hit this yesterday and found it very confusing, even though the solution to the problem is very simple.
Avoid unnecessary hashing
I noticed some stable hashing being done in a non-incremental build. It turns out that some of this is necessary to compute the crate hash, but some of it is not. Removing the unnecessary hashing is a perf win.
