Add clangd flag to include generated header files

This enables clangd to correctly check C files that import Rts.h.
(The added include directory contains ghcautoconf.h et. al.)

upload_ghc_libs: More control over which packages to operate on

Here we add a `--skip` flag to `upload_ghc_libs`, making it easier to
limit which packages to upload. This is often necessary when one package
is not uploadable (e.g. see #22740).

Assume platforms support rpaths if they use either ELF or Mach-O

Not only Linux, Darwin, and FreeBSD support rpaths. Determine the usability
of rpaths based on the object format, not on OS.

RTS linker: Improve compatibility with NetBSD

1. Hint address to NetBSD mmap(2) has a different semantics from that of
   Linux. When a hint address is provided, mmap(2) searches for a free
   region at or below the hint but *never* above it. This means we can't
   reliably search for free regions incrementally on the userland,
   especially when ASLR is enabled. Let the kernel do it for us if we don't
   care where the mapped address is going to be.

2. NetBSD not only hates to map pages as rwx, but also disallows to switch
   pages from rw- to r-x unless the intention is declared when pages are
   initially requested. This means we need a new MemoryAccess mode for
   pages that are going to be changed to r-x.

nativeGen/AArch64: Emit Atomic{Read,Write} inline

Previously the AtomicRead and AtomicWrite operations were emitted as
out-of-line calls. However, these tend to be very important for
performance, especially the RELAXED case (which only exists for
ThreadSanitizer checking).

Fixes #22115.

Fix some correctness issues around tag inference when targeting the bytecode generator.

* Let binders are now always assumed untagged for bytecode.
* Imported referenced are now always assumed to be untagged for bytecode.

Fixes #22840

Introduce warning for loopy superclass solve

Commit aed1974e completely re-engineered the treatment of loopy
superclass dictionaries in instance declarations. Unfortunately,
it has the potential to break (albeit in a rather minor way) user code.

To alleviate migration concerns, this commit re-introduces the old
behaviour. Any reliance on this old behaviour triggers a warning,
controlled by `-Wloopy-superclass-solve`. The warning text explains
that GHC might produce bottoming evidence, and provides a migration
strategy.

This allows us to provide a graceful migration period, alerting users
when they are relying on this unsound behaviour.

Fixes #22912 #22891 #20666 #22894 #22905

rts: make it possible to change mblock size on 32-bit targets

The MBLOCK_SHIFT macro must be the single source of truth for defining
the mblock size, and changing it should only affect performance, not
correctness. This patch makes it truly possible to reconfigure mblock
size, at least on 32-bit targets, by fixing places which implicitly
relied on the previous MBLOCK_SHIFT constant. Fixes #22901.

Documentation: Improve Foldable1 documentation

* Explain foldrMap1, foldlMap1, foldlMap1', and foldrMap1' in greater
  detail, the text is mostly adapted from documentation of Foldable.
* Describe foldr1, foldl1, foldl1' and foldr1' in terms of the above
  functions instead of redoing the full explanation.
* Small updates to documentation of fold1, foldMap1 and toNonEmpty,
  again adapting from Foldable.
* Update the foldMap1 example to lists instead of Sum since this is
  recommended for lazy right-associative folds.

Fixes #22847

fix: Mark ghci Prelude import as implicit

Fixes #22829

In GHCi, we were creating an import declaration for Prelude but we were
not setting it as an implicit declaration. Therefore, ghci's import of
Prelude triggered -Wmissing-import-lists.

Adds regression test T22829 to testsuite

compiler: fix generateCgIPEStub for no-tables-next-to-code builds

generateCgIPEStub already correctly implements the CmmTick finding
logic for when tables-next-to-code is on/off, but it used the wrong
predicate to decide when to switch between the two. Previously it
switches based on whether the codegen is unregisterised, but there do
exist registerised builds that disable tables-next-to-code! This patch
corrects that problem. Fixes #22896.

rts: add the rts_clearMemory function

This patch adds the rts_clearMemory function that does its best to
zero out unused RTS memory for a wasm backend use case. See the
comment above rts_clearMemory() prototype declaration for more
detailed explanation. Closes #22920.
