The conversion to another encoding is now up to the unixlib.

In preparation for calling the audio driver's UNIX functions directly.

242 adds VulkanSC only extensions

Otherwise we will have duplicate members/params with the new 242 xml.

On Ventura, the Rosetta runtime and dyld shared cache now reach down
to 0x7ff7fffb8000 on my system.

On Windows RegEnumValueA() is buggy such that when the value name
buffer is too small, it may way overestimate the required data buffer
size, sometimes returning more than the sufficiently large buffer it was
provided, in which case that buffer is untouched and thus not
NUL-terminated.
So modify the tests to accept this broken result and avoid checking
out-of-bounds data.

When using nulldrv, there's no module to call __wine_set_user_driver and
the user driver is still lazy_load_driver when get_display_driver gets
called during desktop windows creation.

Then, load_desktop_driver fails as it cannot find the not-yet-created
desktop window atom, and fails later explorer.exe window creations such
as the systray window.

Other processes don't suffer from this as they wait for the desktop
window to be fully created, and its atom will be eventually set.

This change makes sure that we succeed in the case nulldrv was selected
by explorer.exe, while still failing in case of error with another user
driver as it would fail to open the right display device GUID.

To match d3d8.

The original patch [1] claims

"WM_SIZE(SIZE_MAXIMIZED) is reliable here. The unreliable behavior
occured only with NOWINDOWCHANGES."

but this doesn't match my testing. Probably when that patch was submitted, this
very fix was applied to the d3d8 tests but forgotten for the d3d9 tests, and
then the wrong conclusions were drawn.
