Introduce ListTuplePuns extension

This implements Proposal 0475, introducing the `ListTuplePuns` extension
which is enabled by default.

Disabling this extension makes it invalid to refer to list, tuple and
sum type constructors by using built-in syntax like `[Int]`,
`(Int, Int)`, `(# Int#, Int# #)` or `(# Int | Int #)`.
Instead, this syntax exclusively denotes data constructors for use with
`DataKinds`.
The conventional way of referring to these data constructors by
prefixing them with a single quote (`'(Int, Int)`) is now a parser
error.

Tuple declarations have been moved to `GHC.Tuple.Prim` and the `Solo`
data constructor has been renamed to `MkSolo` (in a previous commit).
Unboxed tuples and sums now have real source declarations in `GHC.Types`.
Unit and solo types for tuples are now called `Unit`, `Unit#`, `Solo`
and `Solo#`.
Constraint tuples now have the unambiguous type constructors `CTuple<n>`
as well as `CUnit` and `CSolo`, defined in `GHC.Classes` like before.

A new parser construct has been added for the unboxed sum data
constructor declarations.

The type families `Tuple`, `Sum#` etc. that were intended to provide
nicer syntax have been omitted from this change set due to inference
problems, to be implemented at a later time.
See the MR discussion for more info.

Updates the submodule utils/haddock.
Updates the cabal submodule due to new language extension.

    Metric Increase:
        haddock.base

    Metric Decrease:
        MultiLayerModulesTH_OneShot
        size_hello_artifact

Improve error messages coming from non-linear patterns

This enriched the `CtOrigin` for non-linear patterns to include data
of the pattern that created the constraint (which can be quite useful
if it occurs nested in a pattern) as well as an explanation why the
pattern is non-restricted in (at least in some cases).

compiler: start deprecating cmmToRawCmmHook

cmmToRawCmmHook was added 4 years ago in
d561c8f6244f8280a2483e8753c38e39d34c1f01. Its only user is the
Asterius project, which has been archived and deprecated in favor of
the ghc wasm backend. This patch starts deprecating cmmToRawCmmHook by
placing a DEPRECATED pragma, and actual removal shall happen in a
future GHC major release if no issue to oppose the deprecation has
been raised in the meantime.
