This reverts commit 14020f57ee8a8bc8cce58c3fc694cfc00c2d0467.

Reason for revert: Hold off on API breaking change till M62, so we can have several that go out at the same time and we'll have a new origin trial.

> WebVR: Update VRDisplay.GetFrameData to follow the current spec.
> The WebVR 1.1 spec was updated to clarify the behavior of getFrameData.
> Now, GetFrameData should return false unless called within a
