This implements the Loop/Blinn algorithm for quadratic curves
as an optional backend for Qt Quick Shapes, basically distance
fields where the distance to curves are calculated in the
fragment shader.
This means cubic curves are approximated, which will give
varying results, but for many shapes (such as text) this is
efficient and means the shapes can be zoomed indefinitely
while still retaining curvature as well as anti-aliasing
working without MSAA.
Preliminary results give some frame rate improvements
compared to doing MSAA and GeometryRenderer, but the major
improvement is that you can get smooth curves at any zoom
level without re-triangulating the shape.
Note that the renderer currently does not do antialiasing
for straight lines. This would still require MSAA, but at
a lower cost than for GeometryRenderer since there are
much fewer triangles. Adding AA here as well is work in
progress.

The existing CMake API for qml modules had a number of
shortcomings. Refactor it to achieve the following:
- Clearly separate public and internal aspects.
- Re-use code from qtbase for adding plugins and module
targets rather than reimplementing close variations.
- Provide more robust and complete support for qmllint,
qmlcachegen and automatic generation of qmldir files.
- Reduce the steps needed for more common scenarios.
- Encourage the use of separate backing library and plugin
targets.
- Automatically generate the plugin class .cpp file where
possible.
- Specify .qml files directly through qml-specific API
elements rather than assuming they can be extracted
out of a set of resources.
[ChangeLog][QtQml] The qml CMake API has changed from 6.1
and is now out of Technical Preview status. The most
notable change is that .qml files should no longer be
specified as resources, there is dedicated handling for
them in the qt6_add_qml_module(). A related change is
that the qt6_target_qml_files() command has been replaced
by qt6_target_qml_sources(). More complete integration
with qmlcachegen, qmllint and qmldir generation is also
part of the CMake API.

After a symbiotic relationship in Qt 5.14 and 5.15, it is time for
QSGMaterialRhiShader to devour its older sibling and take its place.
This makes the direct OpenGL rendering path disfunctional. All
QSGMaterial Qt 6 TODOs are solved, the API is clean and straightforward
again: a QSGMaterial creates a QSGMaterialShader, no special flags and
options needed. (it's just that QSGMaterialShader now has a slightly
different API)
