Simplify EGLImageFactory and remove caching logic for now
...
The platforms that would most benefit (embedded V4L2 decoders)
either don't use frame pooling or don't synchronize with
modified DMA-BUFs unless eglCreateImage() is called each time.

Fix UB due to missing shader attribute location binding
...
Mesa drivers seem to generally bind attributes in order, but the
proprietary PowerVR driver (pvr) doesn't and renders incorrectly
as a result.

Use EGL+GLES workaround for Nvidia X11
...
We can avoid disabling EGL entirely by forcing Qt to use GLES,
which is not impacted by the black window issue. This lets us
simplify back to EGL everywhere.

Use EGL_VENDOR instead of NV-CONTROL for Nvidia detection
...
The latter will still match on a hybrid system when the iGPU's EGL
implementation is in use. This scenario works properly with EGL
rendering in Qt and SDL, so we want to allow that.

Create a separate X11 Display object for libva
...
Sharing these directly is fraught with concurrency issues that
require extreme care on both sides to avoid spurious X11 errors,
hangs, and other nasty stuff. We can't necessarily depend on SDL,
libva, or the underlying VA drivers to do the right thing here.
Using a new Display (as FFmpeg does for VAAPI and VDPAU) avoids
all these problems.

Reduce per-frame GL calls in EGLRenderer
...
Uniforms are attached to the program object, so they don't need to
be set each time we swap between the YUV shader and the overlay
shader.
Since 0 overlays is by far the most common case and > 1 is highly
unlikely, move the glViewport() call into renderOverlay() to let
us skip it in the common case (and be no worse than today in the
2nd most common case of 1 overlay).
