64760504e7 rhi: Allow testing QRhiRenderPassDescriptors for compatibility
For Metal and Vulkan this needs actual work because that's where
the concept of renderpass descriptors is relevant. GL and D3D can
just return true always.

The big benefit of this is that Qt Quick can now compare renderpass
descriptors via isCompatible() for its pipeline cache (similarly to
how it is already using isLayoutCompatible() for srbs), and so
renderpass descriptors for layers (Item.layer, ShaderEffect) will
typically be compatible and so can pick up pipelines created by other
layers from the cache.

Also add autotests for shader resource binding and renderpass descriptor
compatibility.

f3c37c839c Enable QRhi Metal backend on iOS
While we are at it, remove the Border and MirrorOnce wrap modes that have
not been supported on OpenGL, because they are unsupported with Metal+iOS
as well.

58a67e4e0a rhi: Move to CBOR in QShader and expand the autotest
Binary JSON is said to become deprecated. Therefore, add support
for CBOR. Binary JSON is still supported for deserialization, so
all existing .qsb files will continue to work, as long as the
binaryjson feature is enabled in the Qt build.

Also makes QShaderDescription comparable. This is important for
tests in particular.

A nice side effect of using CBOR is that .qsb files become smaller.
For a typical Qt Quick material shader this can mean a reduction of
300 bytes or more.

8f44da1f55 rhi: Enable the qrhi autotest on WinRT
There is no onscreen support for WinRT in the D3D11 backend yet.
However, offscreen operations (rendering into a texture) should work.
One catch is that there is no D3DCompile available for deployed WinRT
apps. So ship the intermediate format (DXBC output from fxc) in the
.qsb files.

89ec1b3618 rhi: Add support for buffer readbacks
This also marks the beginnings of significantly extending autotesting
of the resource and rendering functionality in QRhi.

Also involves fixing up the buffer operation lists like we did
for textures before. This is to ensure updates and reads on the
same batch execute in the correct order. So just have two lists:
one with buffer, one with texture operations.

Also simplify the struct layouts. No need for those inner structs
with many duplicate members. This reduces the size even, since using a
union was never an option here. Also switch to a VLA, the size is around
253 KB per batch.

The Null backend now keeps track of the QRhiBuffer data so it can return
valid results in readbacks.

53599592e0 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.
