testsuite: 21651 add test for closeFdWith + setNumCapabilities

This bug does not affect windows, which does not use the
base module GHC.Event.Thread.

base: Fix races in IOManager (setNumCapabilities,closeFdWith)

Fix for #21651

Fixes three bugs:

- writes to eventManager should be atomic. It is accessed concurrently by ioManagerCapabilitiesChanged and closeFdWith.
- The race in closeFdWith described in the ticket.
- A race in getSystemEventManager where it accesses the 'IOArray' in
  'eventManager' before 'ioManagerCapabilitiesChanged' has written to
  'eventManager', causing an Array Index exception. The fix here is to
  'yield' and retry.

Updates language extension documentation

Adding a 'Status' field with a few values:
- Deprecated
- Experimental
- InternalUseOnly
- Noting if included in 'GHC2021', 'Haskell2010' or 'Haskell98'

Those values are pulled from the existing descriptions or elsewhere in
the documentation.

While at it, include the :implied by: where appropriate, to provide
more detail.

Fixes #21475

Add support for external static plugins (#20964)

This patch adds a new command-line flag:

  -fplugin-library=<file-path>;<unit-id>;<module>;<args>

used like this:

  -fplugin-library=path/to/plugin.so;package-123;Plugin.Module;["Argument","List"]

It allows a plugin to be loaded directly from a shared library. With
this approach, GHC doesn't compile anything for the plugin and doesn't
load any .hi file for the plugin and its dependencies. As such GHC
doesn't need to support two environments (one for plugins, one for
target code), which was the more ambitious approach tracked in #14335.

Fix #20964

gitlab-ci: Fix ARMv7 build

It appears that the CI refactoring carried out in
5ff690b8474c74e9c968ef31e568c1ad0fe719a1 failed to carry over some
critical configuration: setting the build/host/target platforms and
forcing use of a non-broken linker.
