Care with occCheckExpand in kind of occurrences

Issue #18451 showed that we could get an infinite type, through
over-use of occCheckExpand in the kind of an /occurrence/ of a
type variable.

See Note [Occurrence checking: look inside kinds] in GHC.Core.Type

This patch fixes the problem by making occCheckExpand less eager
to expand synonyms in kinds.

It also improves pretty printing of kinds, by *not* suppressing
the kind on a tyvar-binder like
    (a :: Const Type b)
where type Const p q = p.  Even though the kind of 'a' is Type,
we don't want to suppress the kind ascription.  Example: the
error message for polykinds/T18451{a,b}. See GHC.Core.TyCo.Ppr
Note [Suppressing * kinds].

DynFlags: store printer in TraceBinIfaceReading

We don't need to pass the whole DynFlags, just pass the logging
function, if any.

Remove platform constant wrappers

Platform constant wrappers took a DynFlags parameter, hence implicitly
used the target platform constants. We removed them to allow support
for several platforms at once (#14335) and to avoid having to pass
the full DynFlags to every function (#17957).

Metric Decrease:

Move GHC.Platform into the compiler

Previously it was in ghc-boot so that ghc-pkg could use it. However it
wasn't necessary because ghc-pkg only uses a subset of it: reading
target arch and OS from the settings file. This is now done via
GHC.Platform.ArchOS (was called PlatformMini before).

rts/win32: Exit with EXIT_HEAPOVERFLOW if memory commit fails

Since switching to the two-step allocator, the `outofmem` test fails via
`osCommitMemory` failing to commit. However, this was previously exiting
with `EXIT_FAILURE`, rather than `EXIT_HEAPOVERFLOW`. I think the latter
is a more reasonable exit code for this case and matches the behavior on
POSIX platforms.

testsuite: Normalise WinIO error message differences

Previously the old Windows IO manager threw different errors than WinIO.
We now canonicalise these to the WinIO errors.

Kill off sc_mult and as_mult fields

They are readily derivable from other fields, so this is more
efficient, and less error prone.

Fixes #18494
