This was used to support QFlags f = 0 initialization, but with 0 used
as a pointer literal now considered bad form, it had been changed many
places to QFlags f = nullptr, which is meaningless and confusing.

As usual, keep some QVector overloads around to allow Qt Quick to compile.
Color attachments and vertex input bindings get an at(index) type of
accessor, unlike any other of similar lists. This is because there the
index is significant, and sequential iteration is not the only type of
operation that is performed. Sometimes a lookup based on an index will
be needed as well.

Forcing users to go through a QVector, when in practice they almost
always want to source the data from an initializer list, a QVarLengthArray,
or a plain C array, is not ideal. Especially since we can reason about
the maximum number of elements in the vast majority of use cases for all
the affected lists. QRhiResource is also not copyable so we do not need
the usual machinery offered by containers. So switch to a
QVarLengthArray.
Note that a resource is not a container. The only operations we are
interested in is to be able to source data either via an initializer
list or by iterating on something, and to be able to extract the data,
in case a user wishes to set up another resource based on the existing
one.
In some cases a QVector overload is kept for source compatibility with
other modules (Qt Quick). These may be removed in the future.
Also do a similar QVector->QVarLengthArray change in the srb-related
data in the backends.

This will also cause clearing to 0,0,0,0.
Essential in order to allow fast testing of window transparency
issues in combination with QRhi and the various backends.

As an option. Must opt in via setting ExternalContentsInPass in
the flags for beginFrame(). It is somewhat unfortunate to require
declaring this up front, but forcing using secondary command buffers
always, even though beginExternal() may not be used in many applications,
would be an overkill.

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.
