[WebXR][OpenXR] Input sources not working with hand interaction

https://bugs.webkit.org/show_bug.cgi?id=298021

Reviewed by Adrian Perez de Castro.

Input sources were not properly shown inside WebXR experiences
because their aim and grip poses were retrieved using an incorrect
reference space. We were using the local-floor space but WebXR
expects us to use the local space (i.e. without considering the
floor level).
