This fixes rendering problems on M1 based Macs.
It also unifies the rendering pipeline between macOS and iOS as
much as possible, and avoids an intermediate copy to an FBO,
Since AVPlayerItemVideoOutput produces GL_TEXTURE_RECTANGLE
textures on macOS a new QAbstractVideoBuffer handle has been
added that explicitly maps to GL_TEXTURE_RECTANGLE.
We use this handle type internally in QSGVideoMaterial_Texture
where we know how to blit GL_TEXTURE_RECTANGLE textures.
To maintain compatibility for QAbstractVideoSurface consumers who
expect GL_TEXTURE_2D textures we blit the rectangle texture to
an FBO returned as QAbstractVideoBuffer::GLTextureHandle.
Fixes: QTBUG-89803

When requesting a OGL Core profile via QSurfaceFormat::setDefaultFormat (e.g. to use Qt3D advanced features),
it is no longer possible to render QML Video items. This is because the requested shaders should be _core versions.
This patch adds the core shaders so QtMultimedia stops whining, and bind textures with the proper
format, since GL_LUMINANCE and GL_LUMINANCE_ALPHA are no longer valid in OGL 4.

This patch implements support for rendering of UYVY and YUYV sources when using
QtQuick for preview.
[ChangeLog][QtQuick][Rendering] Support for YUV 4:2:2 8bit has
been implemented for the QtQuick viewfinder.

- Load shader source from resource files.
- Correctly report material types: each material can use different
shaders depending on the video pixel format but it was reporting
a unique material type. This was causing the node to keep using
the same shader even if its pixel format changed.
