CI: JavaScript backend runs testsuite

This MR runs the testsuite for the JS backend. Note that this is a
temporary solution until !9515 is merged.

Key point: The CI runs hadrian on the built cross compiler _but not_ on
the bindist.

Other Highlights:

 - stm submodule gets a bump to mark tests as broken
 - several tests are marked as broken or are fixed by adding more
 - conditions to their test runner instance.

List of working commit messages:

CI: test cross target _and_ emulator

CI: JS: Try run testsuite with hadrian

JS.CI: cleanup and simplify hadrian invocation

use single bracket, print info

JS CI: remove call to test_compiler from hadrian

don't build haddock

JS: mark more tests as broken

Tracked in https://gitlab.haskell.org/ghc/ghc/-/issues/22576

JS testsuite: don't skip sum_mod test

Its expected to fail, yet we skipped it which automatically makes it
succeed leading to an unexpected success,

JS testsuite: don't mark T12035j as skip

leads to an unexpected pass

JS testsuite: remove broken on T14075

leads to unexpected pass

JS testsuite: mark more tests as broken

JS testsuite: mark T11760 in base as broken

JS testsuite: mark ManyUnbSums broken

submodules: bump process and hpc for JS tests

Both submodules has needed tests skipped or marked broken for th JS
backend. This commit now adds these changes to GHC.

See:

HPC: https://gitlab.haskell.org/hpc/hpc/-/merge_requests/21

Process: https://github.com/haskell/process/pull/268

remove js_broken on now passing tests

separate wasm and js backend ci

test: T11760: add threaded, non-moving only_ways

test: T10296a add req_c

T13894: skip for JS backend

tests: jspace, T22333: mark as js_broken(22573)

test: T22513i mark as req_th

stm submodule: mark stm055, T16707 broken for JS

tests: js_broken(22374) on unpack_sums_6, T12010

dont run diff on JS CI, cleanup

fixup: More CI cleanup

fix: align text to master

fix: align exceptions submodule to master

CI: Bump DOCKER_REV

Bump to ci-images commit that has a deb11 build with node. Required for
!9552

testsuite: mark T22669 as js_skip

See #22669

This test tests that .o-boot files aren't created when run in using the
interpreter backend. Thus this is not relevant for the JS backend.

testsuite: mark T22671 as broken on JS

See #22835

base.testsuite: mark Chan002 fragile for JS

see #22836

revert: submodule process bump

bump stm submodule

New hash includes skips for the JS backend.

testsuite: mark RnPatternSynonymFail broken on JS

Requires TH:
 - see !9779
 - and #22261

compiler: GHC.hs ifdef import Utils.Panic.Plain
