ghc-toolchain: Toolchain Selection

This commit integrates ghc-toolchain, the brand new way of configuring
toolchains for GHC, with the Hadrian build system, with configure, and
extends and improves the first iteration of ghc-toolchain.

The general overview is

* We introduce a program invoked `ghc-toolchain --triple=...` which, when run,
  produces a file with a `Target`. A `GHC.Toolchain.Target.Target`
  describes the properties of a target and the toolchain (executables
  and configured flags) to produce code for that target

* Hadrian was modified to read Target files, and will both
  * Invoke the toolchain configured in the Target file as needed
  * Produce a `settings` file for GHC based on the Target file for that stage

* `./configure` will invoke ghc-toolchain to generate target files, but
  it will also generate target files based on the flags configure itself
  configured (through `.in` files that are substituted)

  * By default, the Targets generated by configure are still (for now) the ones used by Hadrian

  * But we additionally validate the Target files generated by
    ghc-toolchain against the ones generated by configure, to get a head
    start on catching configuration bugs before we transition
    completely.

  * When we make that transition, we will want to drop a lot of the
    toolchain configuration logic from configure, but keep it otherwise.

* For each compiler stage we should have 1 target file (up to a stage compiler we can't run in our machine)
  * We just have a HOST target file, which we use as the target for stage0
  * And a TARGET target file, which we use for stage1 (and later stages, if not cross compiling)
  * Note there is no BUILD target file, because we only support cross compilation where BUILD=HOST
  * (for more details on cross-compilation see discussion on !9263)

Add flag to enable/disable ghc-toolchain based configurations

This flag is disabled by default, and we'll use the
configure-generated-toolchains by default until we remove the toolchain
configuration logic from configure.

Split ghc-toolchain executable to new packge

In light of #23690, we split the ghc-toolchain executable out of the
library package to be able to ship it in the bindist using Hadrian.

Ideally, we eventually revert this commit.

Ship ghc-toolchain in the bindist

Add the ghc-toolchain binary to the binary distribution we ship to
users, and teach the bindist configure to use the existing ghc-toolchain.

Kill off gen_bytearray_addr_access_ops.py

The relevant primop descriptions are now
generated directly by genprimopcode.

This makes progress toward fixing #23490, but it is not
a complete fix since there is more than one way in which
cabal-reinstall (hadrian/build build-cabal) is broken.

Fix pretty printing of WARNING pragmas

There is still something quite unsavoury going on with WARNING pragma
printing because the printing relies on the fact that for decl
deprecations the SourceText of WarningTxt is empty. However, I let that
lion sleep and just fixed things directly.

Fixes #23465

ci-images: Bump to commit which has 9.6 image

The test-bootstrap job has been failing for 9.6 because we accidentally

rts: Simplify atomicModifyMutVar2# implementation

Previously we would perform a redundant load in the non-threaded RTS in
atomicModifyMutVar2# implementation for the benefit of the non-moving
GC's write barrier. Eliminate this.
