Introduce the Qt graphics abstraction as private QtGui helpers

Comes with backends for Vulkan, Metal, Direct3D 11.1, and OpenGL (ES).

All APIs are private for now.

Shader conditioning (i.e. generating a QRhiShader in memory or on disk
from some shader source code) is done via the tools and APIs provided
by qt-labs/qtshadertools.

The OpenGL support follows the cross-platform tradition of requiring
ES 2.0 only, while optionally using some (ES) 3.x features. It can
operate in core profile contexts as well.

Task-number: QTBUG-70287
