CorePrep: Eliminate EmptyCase and unsafeEqualityProof in CoreToStg instead
We eliminate EmptyCase by way of `coreToStg (Case e _ _ []) = coreToStg e` now.
The main reason is that it plays far better in conjunction with eta expansion
(as we aim to do for arguments in CorePrep, #23083), because we can discard
any arguments, `(case e of {}) eta == case e of {}`, whereas in `(e |> co) eta`
it's impossible to discard the argument.

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

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]

We used to bundle all children of the parent Avail with things that
aren't the parent, e.g. with
class C a where
type T a
meth :: ..
we would bundle the whole Avail (C, T, meth) with all of C, T and meth,
instead of only with C.

Metric Increase:

T8095 ghc/alloc decreased on x86_64, but increased on aarch64.
T13386 ghc/alloc decreased on x86_64-windows, but increased on other platforms.
Neither has anything to do with `foldl'`, so I conclude that both are flaky.

In the Lint failure in #23938, we start with a coercion Refl :: T a ~R T a,
and call mkSelCo (SelTyCon 1 nominal) Refl.
The function incorrectly returned Refl :: a ~R a. The returned role
should be nominal, according to the SelCo rule:
co : (T s1..sn) ~r0 (T t1..tn)
r = tyConRole tc r0 i
----------------------------------
SelCo (SelTyCon i r) : si ~r ti
In this test case, r is nominal while r0 is representational.
