[WebXR Layers] Nothing is rendered in threejs XR examples
https://bugs.webkit.org/show_bug.cgi?id=314556
Reviewed by Dan Glastonbury.
Soon after creating a projection layer the size of the textures backing
that layer should be available and exposed to JS. However the current
code was waiting for the first texture to be created and available to
set the size. It's fine to set the available size at creation time as
specs describes them as the "recommended width/height of color textures
for this layer" based on what the device says and the scale factor.
That was the reason why threejs examples were failing, because they were
checking the size of the textures soon after creating the layer without
waiting for the first rAF.
