This commit implements [amendment 604](https://github.com/ghc-proposals/ghc-proposals/pull/604/)
to [GHC proposal 448](https://github.com/ghc-proposals/ghc-proposals/pull/448)
by removing the implication of language extensions
ScopedTypeVariables => TypeAbstractions
To limit breakage, we now allow type arguments in constructor patterns
when both ScopedTypeVariables and TypeApplications are enabled, but
we emit a warning notifying the user that this is deprecated behaviour
that will go away starting in GHC 9.12.
Fixes #23776

This commit accepts testsuite changes for the changes in the previous
commit, which mean that TypeAbstractions is no longer implied by

Resolves #23540, #23120
This adds spans to certain expressions in the typechecker and renamer,
and lets 'toHie' make use of those spans. Therefore the relevant
evidence uses for the following syntax will now show up under the
expected nodes in 'HieAst's:
- Overloaded literals ('IsString', 'Num', 'Fractional')
- Natural patterns and N+k patterns ('Eq', 'Ord', and instances from the
overloaded literals being matched on)
- Arithmetic sequences ('Enum')
- Monadic bind statements ('Monad')
- Monadic body statements ('Monad', 'Alternative')
- ApplicativeDo ('Applicative', 'Functor')
- Overloaded lists ('IsList')
Also see Note [Source locations for implicit function calls]
In the process of handling overloaded lists I added an extra 'SrcSpan'
field to 'VAExpansion' - this allows us to more accurately reconstruct
the locations from the renamer in 'rebuildHsApps'. This also happens to
fix #23120.
See the additions to Note [Looking through HsExpanded]

- Builtin.PrimOps: ReturnsAlg was used only for unboxed tuples.
Rename to ReturnsTuple.
- Builtin.Utils: use SDoc for a panic message.
The comment about <<details unavailable>> was obsoleted by e8d356773b56.
- TagCheck: fix wrong logic. It was zipping a list 'args' with its
version 'args_cmm' after filtering.
- Core.Type: remove an outdated 1999 comment about unlifted polymorphic types
- hadrian: remove leftover debugging print

We used to export getTcSInerts and setTcSInerts from GHC.Tc.Solver.Monad.
These got renamed to getInertSet/setInertSet in e1590ddc. That commit also removed
the export of setInertSet, but that function is useful for the GHC API.
