Change XRSession.getInputSources() method to inputSources attribute

In order to make the input sources list into a live object, which can be
updatd in place, we needed to make it no longer return a FrozenArray.
This requires changing it to it's own XRInputSourceArray type, and
changing how it is accessed from a getter to an attribute.

Note that this change does not actually make the inputSources object
a "live" object just yet, but is simply all of the idl/interface changes
necessary for that work to happen.
