Starting to replace QObject pointers with QJSValue that allows dynamic
properties to be added to the the returned objects from QCanvas3D API.
This makes the implementation more compatible with WebGL code out there.

All uniform??va functions made internal, uniform??v functions now accept
QJSValue as input and dynamically detect the parameter type.
Examples updated accordingly.

Buffer3D, Program3D, Shader3D and UniformLocation3D types now changed
to use QJSValue.

Multisampling is fully available in ES 3.0+ so extend the condition.
(well technically we should check for the relevant extensions on GLES2
too since embedded/mobile devices will have it, but let's leave that for later)

Similarly, forcing ES 2.0 for the shared context when the original was ES 3.x is
not necessarily a good idea. So do like desktop GL and request the same version.
