While completely untested, at least this makes it work "in theory"
again. Before it'd listen to signals on the stage, but have an incorrect
type signature to handle the test paint procedures, meaning it'd
probably crash or cause memory corruptions.
What was needed was a signal which in the callback the test could call
some cogl functions to paint on the framebuffer. While there is no such
signal on the stage, and the ClutterActor::paint signal (which they
probably used in the past) is long gone, lets add a "test actor" that is
just a wrapper that adds that paint signal with a paint context.
The tests that need it are changed to add this actor to the stage, and
to listen to the paint signal on the actor instead of incorrectly
listening on stage signals.

This means we can eliminate the use of scattered singletons that isn't
added by the tests or the test framework itself.
tests: Don't get backend from old singleton getter
Either use the ownership chain, or the explicit test context instance
pointer.
tests/wayland: Pass context to test client constructor
So that we can get the Wayland compositor directly from the context.
tests: Don't get display from singleton
tests/client: Make test client carry a context pointer
tests/runner: Have test cases carry a context pointer
tests/wayland/test-driver: Get backend from context

As with the compositor type enum, also have the X11 display policy enum,
as it's also effectively part of the context configuration. But as with
the compositor type, move it to a header file for enums only, and since
this is a private one, create a private variant meta-enums.h.

The clutter tests neeed to start and stop, thus uses their own main loop
instead of the one in MetaContext. Shouldn't matter, since nothing
in mutter should happen that makes the test self-terminate from inside
mutter.

With Xwayland initialization going async, these errors will seep
into the parts controlled by g_test*(), resulting in the harmless
errors about DBus names not acquired turned fatal.
Set an error log handler, and specifically ignore those.

This is inspired by 98892391d7 where the usage of
`g_signal_handler_disconnect()` without resetting the corresponding
handler id later resulted in a bug. Using `g_clear_signal_handler()`
makes sure we avoid similar bugs and is almost always the better
alternative. We use it for new code, let's clean up the old code to
also use it.
A further benefit is that it can get called even if the passed id is
0, allowing us to remove a lot of now unnessecary checks, and the fact
that `g_clear_signal_handler()` checks for the right type size, forcing us
to clean up all places where we used `guint` instead of `gulong`.
No functional changes intended here and all changes should be trivial,
thus bundled in one big commit.

And add the necessary glue so those initialize a X11 clutter backend.
This should get Clutter tests that are dependent on windowing to work
again, thus they were enabled back again.
