Allow WARNING pragmas to be controlled with custom categories

Closes #17209. This implements GHC Proposal 541, allowing a WARNING
pragma to be annotated with a category like so:

    {-# WARNING in "x-partial" head "This function is undefined on empty lists." #-}

The user can then enable, disable and set the severity of such warnings
using command-line flags `-Wx-partial`, `-Werror=x-partial` and so on.  There
is a new warning group `-Wextended-warnings` containing all these warnings.
Warnings without a category are treated as if the category was `deprecations`,
and are (still) controlled by the flags `-Wdeprecations`
and `-Wwarnings-deprecations`.

Updates Haddock submodule.

nativeGen/AArch64: Fix bitmask immediate predicate

Previously the predicate for determining whether a logical instruction
operand could be encoded as a bitmask immediate was far too
conservative. This meant that, e.g., pointer untagged required five
instructions whereas it should only require one.

Fixes #23030.
