Extract `DepKindVTable` constructors to their own module
This is a fairly substantial chunk of code in `rustc_query_impl::plumbing` that mostly doesn't need to be inside a macro at all.
The part that does need to be in a macro is the declaration of a named vtable constructor function for each query. I have extracted that into its own separate call to `rustc_middle::rustc_with_all_queries!` in the new module, so that dep-kind vtable construction is almost entirely confined to `rustc_query_impl::dep_kind_vtables`.
There should be no change to compiler behaviour.

Add 2048-bit HvxVectorPair support to Hexagon SIMD ABI checks
Previously, rustc rejected HvxVectorPair types in function signatures because the HEXAGON_FEATURES_FOR_CORRECT_FIXED_LENGTH_VECTOR_ABI array only had entries for vectors up to 1024 bits. This caused the ABI checker to emit "unsupported vector type" errors for 2048-bit HvxVectorPair (used in 128-byte HVX mode).
Add 2048 byte entry to allow HvxVectorPair to be passed in extern "C" funcs when the hvx-length128b is enabled.
sparc64: enable abi compatibility test
fixes https://github.com/rust-lang/rust/issues/115336
We can now remove the exceptions for sparc64 from the abi compatibility tests (since https://github.com/rust-lang/rust/pull/142680).
I was also able to remove a cfg for mips64. The remaining (tested) issues seem to be around how `f64` is handled there.

Don't use `DepContext` in `rustc_middle::traits::cache`
- A nice little simplification unlocked by https://github.com/rust-lang/rust/pull/152199.
---
This code is now in `rustc_middle`, and doesn't need any non-trivial methods, so it can just use `TyCtxt` directly instead.
Collect active query jobs into struct `QueryJobMap`
This PR encapsulates the existing `QueryMap` type alias into a proper struct named `QueryJobMap`, which is used by code that wants to inspect the full set of currently-active query jobs.
Wrapping the query job map in a struct makes it easier to see how other code interacts with the map, and also lets us change some free functions for map lookup into methods.
We also do a renaming pass to consistently refer to the query job map as `job_map`, or as `job_map_out` in the places where it's a mutable out-parameter.
There should be no change to compiler behaviour.

Change query proc macro to be more rust-analyzer friendly
This changes the query proc macro to be more rust-analyzer friendly.
- Types in the macro now have a proper span
- Some functions have their span hidden so they don't show up when hovering over the query name
- Added a hint on the provider field on how to find providers. That is shown when hovering over the query name
- Linked query name to the provider field on all queries, not just ones with caching
- Added tooltip for the query modifiers by linking to the new types in `rustc_middle:::query::modifiers`
Compute localized outlives constraints lazily
This PR rewrites the loan liveness algorithm to compute localized constraints lazily during traversal, to avoid the sometimes costly conversion and indexing happening in the current eager algorithm (or for now as well, the need to reshape the liveness data to better list regions live at a given point).
It thus greatly reduces the current alpha overhead, although it wasn't entirely removed of course (we're obviously doing more work to improve precision): the worst offending benchmark has a +5-6% wall-time regression — but icounts are worse looking (+13%) rn.
Best reviewed per-commit, as steps are in sequence to simplify the process or unify some things.

Add 2048 byte entry to allow HvxVectorPair to be passed

now that we need to hold the graph for MIR dumping, and the associated
data to traverse it, there is no difference between the main context and
diagnostics context, so we merge them.
we may need to traverse the lazy graph multiple times:
- to record loan liveness
- to dump the localized outlives constraint in the polonius MIR dump
to do that we extract the previous loan liveness code into an abstract
traversal + visitor handling the liveness-specific parts, while the MIR
dump will be able to record constraints in its own visitor.
now that the analysis is only using the regular liveness shape, we don't
need to store it transposed, and thus don't need the container where it
was stored: the liveness context would be alone in the polonius context.
we thus remove the latter, and rename the former.
