Have feature flags as appropriate. OpenGL is causing a mess here
but let's support what we can since some of this will become relevant
in more sophisticated mesh drawing cases with 3D in particular.

...but this will vary between backends, or in some cases
even between implementations of the same API.
Point size is settable only via the vertex shader (gl_PointSize).
It is silently ignored with D3D and HLSL.
Line widths other than 1 are supported only on OpenGL and Vulkan.
(but this is in fact deprecated with GL and optional with Vulkan)
Add QRhi::Feature values for both.
The line width is now settable on QRhiGraphicsPipeline. It is not a
dynamic state since the static, per-pipeline width is good enough for
most cases. (and the feature is not supported on half of the backends
anyways so it will get limited use in practice).

D3D11 and GL (4.3+, ES 3.1+) will come separately at a
later time.

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.
