Some recent shader generation routines require the information of
the existence of attributes. It will be used for checking if the mesh
has a specific attribute or not.

g_renderContexts global static caches the render context interface
for each window. However, there was no mechanism to clear the cache
in case the interface gets deleted, leading to corrupted interface
being returned from the cache in the future. Now the interface is
cleared from the cache upon its deletion.

This fixes QML Designer live preview crash.

The decision to remove mesh bvh data, which presumably is only used

not, as the same mesh can be used by multiple models.

Custom materials didn't correctly detect the window in importScene
case. Also fixed the property detection in cases there is more than
one superclass on top of the custom material base class.

This isn't a complete fix for QTBUG-83889, but it at least makes it
possible to use custom materials in Design Studio without crashing
the QML puppet. Now the custom material shows up properly on either
form editor or in 3D edit view (the latter in cases where QML document
doesn't have View3D using the material to hijack the material shader).
Since you don't get both at the same time, editing the scene with
custom materials is still painful.

The QtOpenGLExtensions was exposed in the public library
interface of QtQuick3D causing it to be linked into user applications,
the effect of this is that applications built (in debug mode) with Qt from
our binary installer will fail to build, as the build system will attempt
to pull in the debug version of QtOpenGLExtensions, which is not shipped
with the binary installed version of Qt (that is a separate issue).

Instead of attempting to test odd cases with no usefulness in practice, like
wanting to clear in combination Inline or Overlay, switch those to "transparent"

Similarly to what we did with the examples: with the RHI-based rendering
path the View3D's clearColor has no effect when the renderMode is not
Offscreen. So just set that color to match the QQuickWindow's color.
That way the end result is the same regardless of who does the clear.

The math was a bit busted, and QML needed to QQuick3DNode to be
registered.

Quaternion.lookAt(...)'s function signature changed a bit to accommodate
some default arguments.  The return of this function is the relative
transformation that needs to be made to get the correct lookat value, so
to use it you either need to use the default forward/up vectors to get
the global rotation, or the current forward/up vectors to get the
relative change.

Implement QQuick3DCamera::lookAt() using Euler angles to avoid
rolling the camera.
