World.HasBounds returns true even if xrGetReferenceSpaceBoundsRect failed

[keveleigh]

Description

Running on a device that currently supports stage space but doesn't support xrGetReferenceSpaceBoundsRect is causing my app to act on undefined data from World.BoundsSize.

Looking at the code, it properly checks for success and availability, but then returns true regardless of that success path.

StereoKit/StereoKitC/xr_backends/openxr.cpp

Lines 140 to 152 in 646afee

	XrExtent2Df bounds;
	XrResult res = xrGetReferenceSpaceBoundsRect(xr_session, XR_REFERENCE_SPACE_TYPE_STAGE, &bounds);
	if (XR_SUCCEEDED(res) && res != XR_SPACE_BOUNDS_UNAVAILABLE) {
	out_size->x = bounds.width;
	out_size->y = bounds.height;
	log_diagf("Bounds updated: %.2g<~BLK>x<~clr>%.2g at (%.1g,%.1g,%.1g) (%.2g,%.2g,%.2g,%.2g)",
	out_size->x, out_size->y,
	out_pose->position .x, out_pose->position .y, out_pose->position .z,
	out_pose->orientation.x, out_pose->orientation.y, out_pose->orientation.z, out_pose->orientation.w);
	}
	return true;

I guess thinking this through, this is maybe an interesting case, because the BoundsPose is valid but BoundsSize is not. Do we want HasBounds to be true iif both pose and size are valid? If it's okay to have just one or the other, we might need some way to message that to the app.
