utils: remove unused lndir from tree

Ever since the removal of the make build system, the in tree lndir
hasn't been actually built, so this patch removes it.

Implement Proposal 0475

This introduces the extension ListTuplePuns, 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

rts: avoid checking bdescr of value outside of Haskell heap

In nonmovingTidyWeaks we want to check if the key of a weak pointer
lives in the non-moving heap. We do this by checking the flags of the
block the key lives in. But we need to be careful with values that live
outside the Haskell heap, since they will lack a block descriptor and
looking for one may lead to a segfault. In this case we should just
accept that it isn't on the non-moving heap.

Resolves #24492
