hotplug_loop_init() calls pw_context_new(), which creates a thread
internally (for the "data loop"). It also creates a thread of its own,
the `hotplug_loop`.
Both of these threads are running code from libpipewire, so before we
can allow the Pipewire library to be unloaded, we need to destroy
the context with pw_context_destroy() and destroy the `hotplug_loop`
with pw_thread_loop_destroy().

On most Unix platforms supported by SDL, the canonical name used to load
a library at runtime includes its ABI major version, and the name
without a version is not guaranteed to exist on non-developer systems.
libX11-xcb.so.1 is correct on Linux, and probably on other Unix
platforms like FreeBSD.
A notable exception is OpenBSD, which apparently does not use
ABI-suffixed names, so continue to use libX11-xcb.so there.

When debugging crash reports, it's helpful to know which thread is
associated with which external library.
Linux limits the length of a thread name to 15 bytes (not including the
zero-termination), so abbreviate Pipewire to "pw" and hotplug to "plug"
to fit the desired information into the allowed space.

We make sure we initialize XInput first, so that anything checking whether it's enabled gets a valid result based on whether we were able to load it or not.
- CreateEventEx() is guarded by _WIN32_WINNT >= 0x0600:
In SDL_gpu_d3d12.c, include core/windows/SDL_windows.h
that defines _WIN32_WINNT properly to account for that
- DXGIInfoQueue stuff is not available in all toolchains
such as mingw-w64 version 8.0.3
- SDL_gpu_d3d11.c: _WIN32 is always defined by MinGW, as
is the case for all windows-targeting compilers, so it
doesn't guarantee absence of DXGIInfoQueue stuff:
rely on __IDXGIInfoQueue_INTERFACE_DEFINED__, as it is
done elsewhere.
Fixes: https://github.com/libsdl-org/SDL/issues/10705 .
Allow setting a parent/child relationship on toplevel windows, which allows raising sets of windows together, and allows child windows to always float above their parents.
Modal windows are now set by setting the parent, then toggling modal status, as the previous interface duplicated functionality now handled by SDL_SetWindowParent().
