Move layerX/layerY from UIEvent to MouseEvent

These are non-standard properties, but if they are standardized it will be on MouseEvent, see w3c/uievents#135. Furthermore, it's only on MouseEvent that these properties ever return something other than zero. The apparent removal in Chrome 45 was caused by the move from UIEvent to MouseEvent in Chromium: https://bugs.chromium.org/p/chromium/issues/detail?id=503276 Since MouseEvent inherits from UIEvent, we can ignore this prototype move in BCD, per our guidelines: https://github.com/mdn/browser-compat-data/blob/main/docs/data-guidelines.md#apis-moved-on-the-prototype-chain
