rts: cleanup inlining logic

This patch removes pre-C11 legacy code paths related to
INLINE_HEADER/STATIC_INLINE/EXTERN_INLINE macros, ensure EXTERN_INLINE
is treated as static inline in most cases (fixes #24945), and also
corrects the comments accordingly.

JS: establish single source of truth for symbols

In pursuit of: #22736.

This MR moves ad-hoc symbols used throughout the js backend into a
single symbols file. Why? First, this cleans up the code by removing
ad-hoc strings created on the fly and therefore makes the code more
maintainable. Second, it makes it much easier to eventually type these
identifiers.

rts: replace ad-hoc MYTASK_USE_TLV with proper CC_SUPPORTS_TLS

This patch replaces the ad-hoc `MYTASK_USE_TLV` with the
`CC_SUPPORTS_TLS` macro. If TLS support is detected by autoconf, then
we should use that for managing `myTask` in the threaded RTS.

Add `__GLASGOW_HASKELL_ASSERTS_IGNORED__` as CPP macro name if `-fasserts-ignored is set.

This allows users to create their own Control.Exception.assert-like functionality that
does something other than raising an `AssertFailed` exception.

Fix a QuickLook bug

This MR fixes the bug exposed by #24676.  The problem was that
quickLookArg was trying to avoid calling tcInstFun unnecessarily; but
it was in fact necessary.  But that in turn forced me into a
significant refactoring, putting more fields into EValArgQL.

Highlights: see Note [Quick Look overview] in GHC.Tc.Gen.App

* Instantiation variables are now distinguishable from ordinary
  unification variables, by level number = QLInstVar. This is
  treated like "level infinity".  See Note [The QLInstVar TcLevel]
  in GHC.Tc.Utils.TcType.

* In `tcApp`, we don't track the instantiation variables in a set Delta
  any more; instead, we just tell them apart by their level number.

* EValArgQL now much more clearly captures the "half-done" state
  of typechecking an argument, ready for later resumption.
  See Note [Quick Look at value arguments] in GHC.Tc.Gen.App

* Elminated a bogus (never used) fast-path in
  GHC.Tc.Utils.Instantiate.instCallConstraints
  See Note [Possible fast path for equality constraints]

Many other small refactorings.

haddock: Fix hyperlinker source urls (#24907)

This fixes a bug introduced by f56838c36235febb224107fa62334ebfe9941aba Links to
external modules in the hyperlinker are uniformly generated using splicing the
template given to us instead of attempting to construct the url in an ad-hoc manner.

Prioritise nominal equalities

The main payload of this patch is

* Prioritise nominal equalities in the constraint solver. This
  ameliorates the incompleteness of solving for representational
  constraints over newtypes: see #24887.

   See (EX2) in Note [Decomposing newtype equalities] in
   GHC.Tc.Solver.Equality

In doing this patch I tripped over some other things that I refactored:

* Move `isCoVarType` from `GHC.Core.Type` to `GHC.Core.Predicate`
  where it seems more at home.

* Clarify the "rewrite role" of a constraint.  I was very puzzled
  about what the role of, say `(Eq a)` might be, but see the new
  Note [The rewrite-role of a constraint].

  In doing so I made predTypeEqRel crash when given a non-equality.
  Usually it expects an equality; but it was being mis-used for
  the above rewrite-role stuff.

rts: use page sized mblocks on wasm

This patch changes mblock size to page size on wasm. It allows us to
simplify our wasi-libc fork, makes it much easier to test third party
libc allocators like emmalloc/mimalloc, as well as experimenting with
threaded RTS in wasm.

Various fixes to type-tidying

This MR was triggered by #24868, but I found a number of bugs
and infelicities in type-tidying as I went along.  Highlights:

* Fix to #24868 is in GHC.Tc.Errors.report_unsolved: avoid
  using the OccNames of /bound/ variables when tidying /free/
  variables; see the call to `tidyAvoiding`.  That avoid the
  gratuitous renaming which was the cause of #24868. See
     Note [tidyAvoiding] in GHC.Core.TyCo.Tidy

* Refactor and document the tidying of open types.
  See GHC.Core.TyCo.Tidy
     Note [Tidying open types]
     Note [Tidying is idempotent]

* Tidy the coercion variable in HoleCo. That's important so
  that tidied types have tidied kinds.

* Some small renaming to make things consistent.  In particular
  the "X" forms return a new TidyEnv.  E.g.
     tidyOpenType  :: TidyEnv -> Type -> Type
     tidyOpenTypeX :: TidyEnv -> Type -> (TidyEnv, Type)

Implement Data.List.compareLength and Data.List.NonEmpty.compareLength

`compareLength xs n` is a safer and faster alternative to `compare (length xs) n`.
The latter would force and traverse the entire spine (potentially diverging),
while the former traverses as few elements as possible.

The implementation is carefully designed to maintain as much laziness as possible.

As per https://github.com/haskell/core-libraries-committee/issues/257
