RTS configure: Move over mem management checks

These are for heap allocation, a strictly RTS concern.

All of this should boil down to `AC_DEFINE` not `AC_SUBST`, so it
belongs in the RTS configure and should be safe to move without
modification.

The RTS configure one has a new
```
AC_CHECK_SIZEOF([void *])
```
that the top-level configure version didn't have, so that
`ac_cv_sizeof_void_p` is defined. Once more code is moved over in latter
commits, that can go away.

Progress towards #17191

RTS configure: Move over `__thread` check

This used by (@bgamari thinks) the `GCThread` abstraction in the RTS.

All of this should boil down to `AC_DEFINE` not `AC_SUBST`, so it
belongs in the RTS configure and should be safe to move without
modification.

RTS configure: Move over misc function checks

These are for general use in the RTS.

All of this should boil down to `AC_DEFINE` not `AC_SUBST`, so it
belongs in the RTS configure and should be safe to move without
modification.

RTS configure: Move over `eventfd` check

This check is for the RTS part of the event manager and has a
corresponding part in `base`.

All of this should boil down to `AC_DEFINE` not `AC_SUBST`, so it
belongs in the RTS configure and should be safe to move without
modification.

Split `FP_CHECK_PTHREADS` and move part to RTS configure

`NEED_PTHREAD_LIB` is unused since
3609340743c1b25fdfd0e18b1670dac54c8d8623 (part of the make build
system), and so is no longer defined.

nativeGen: section flags for .text$foo only

Commit 3ece9856d157c85511d59f9f862ab351bbd9b38b, was supposed to fix
#22834 in !9810.

It does however add "xr" indiscriminatly to .text sections
even if splitSections is disabled. This leads to the assembler saying:

ghc_1.s:7849:0: error:
     Warning: Ignoring changed section attributes for .text
     |
7849 | .section .text,"xr"
     | ^

base: Introduce move modules into src

The only non-move changes here are whitespace changes to pass the
`whitespace` test and a few testsuite adaptations.

CgUtils.fixStgRegStmt respect register width

This change ensure that the reg + offset computation is always of the
same size.  Before this we could end up with a 64bit register, and then
add a 32bit offset (on 32bit platforms).  This not only would fail type
sanity checking, but also incorrectly truncate 64bit values into 32bit
values silently on 32bit architectures.

[PEi386 linker] Bounds check and null-deref guard

We should resonably be able to expect that we won't exceed the number of
sections if we assume to be dealing with legal object files. We can however
not guarantee that we get some negative values, and while we try to
special case most, we should exclude negative indexing into the sections
array.

We also need to ensure that we do not try to derefences targetSection,
if it is NULL, due to the switch statement.
