Optional support for QSGMapboxGLRenderNode

QSGMapboxGLRenderNode support is experimental: It doesn't support
QQuickItem transforms nor stencil clipping.

By default, QSGMapboxGLTextureNode is enabled. The user can select
QSGMapboxGLRenderNode by setting 'mapboxgl.use_fbo' plugin parameter
to 'false'.
