Quasi-support for offscreen surface on WASM
Since context sharing is not currently supported with WebGL, offscreen
contexts have a limited usability on Qt for WASM.
If a context is shared, use the same underlaying WebGL context so that
the two can actually share resources. This is not full-blown context
sharing by any means but it makes e.g. the Open GL widget work as the
readback texture for it is 'shared' between the virtual Qt contexts.
If no sharing is desired, we use an OffscreenCanvas and actually create
a separate WebGL context.
Fixes: QTBUG-107558
Pick-to: 6.5
