Generate Addr# access ops programmatically
The existing utils/genprimopcode/gen_bytearray_ops.py was
relocated and extended for this purpose. Additionally, hadrian
now knows about this script and uses it when generating primops.txt

ghcup-metadata: Only add Nightly tag when replacing LatestNightly
Previously we were always adding the Nightly tag, but this led to all
the previous builds getting an increasing number of nightly tags over
time. Now we just add it once, when we remove the LatestNightly tag.

Invisible binders in type declarations (#22560)
This patch implements @k-binders introduced in GHC Proposal #425
and guarded behind the TypeAbstractions extension:
type D :: forall k j. k -> j -> Type
data D @k @j a b = ...
^^ ^^
To represent the new syntax, we modify LHsQTyVars as follows:
- hsq_explicit :: [LHsTyVarBndr () pass]
+ hsq_explicit :: [LHsTyVarBndr (HsBndrVis pass) pass]
HsBndrVis is a new data type that records the distinction between
type variable binders written with and without the @ sign:
data HsBndrVis pass
= HsBndrRequired
| HsBndrInvisible (LHsToken "@" pass)
The rest of the patch updates GHC, template-haskell, and haddock
to handle the new syntax.
Parser:
The PsErrUnexpectedTypeAppInDecl error message is removed.
The syntax it used to reject is now permitted.
Renamer:
The @ sign does not affect the scope of a binder, so the changes to
the renamer are minimal. See rnLHsTyVarBndrVisFlag.
Type checker:
There are three code paths that were updated to deal with the newly
introduced invisible type variable binders:
1. checking SAKS: see kcCheckDeclHeader_sig, matchUpSigWithDecl
2. checking CUSK: see kcCheckDeclHeader_cusk
3. inference: see kcInferDeclHeader, rejectInvisibleBinders
Helper functions bindExplicitTKBndrs_Q_Skol and bindExplicitTKBndrs_Q_Tv
are generalized to work with HsBndrVis.
Updates the haddock submodule.
Metric Increase:

Capture scoped kind variables at type-checking phase (#16635)
Like descibed in new Note [A scoping errors during type check] in
GHC.Tc.Types, I made ScopedTypeVariables work on type level like in
term level.
For now that only means, that the error about kind variables scoped
into type are rejected at the elaboration time, because we can't
generalize the type by adding type-level lambda - we simply have no one.
