Tracing/QmlProfiler: Prepare for porting of shaders to Qt 6

Browse Source 
This change touches up the shader handling code in Tracing and
QmlProfiler in order to pave the way for the pending porting of
the shaders to Qt 6.

- Use QSGGeometry::Attribute::createWithAttributeType instead of
  QSGGeometry::Attribute::create
- Undefine some fields that are unused in Qt 6
- Add a couple of comments to document the relation between C++
  variables and shader attributes
- Extract some code into functions
