Fixes XRObjectSpace::MojoFromNative() returning incorrect (inverted)
results. Fixes XRSession::CreateAnchor() incorrectly assuming that
passed in initial pose is expressed relative to mojo, and creating
resolver too early in the method.

Other minor refactorings:
- XRHitTestResult::getPose() - no functional changes, clarified naming
- XRObjectSpace now assumes that T has MojoFromObject() method
- Changed XRPlane and XRAnchor - renamed poseMatrix() to
MojoFromObject() to match the changed expectations in XRObjectSpace.
