Make BBH parameter to SkRecordComputeLayers and SkRecordFillBounds optional

Chromium creates a picture to contain their picture pile in order to use MultiPictureDraw. They currently do not create a bounding box for that picture but I still need layer information for it. This change allows Chromium to continue without a BBH but still have layer information.

In the future, the brute force BBH might be suitable for their use case.

Please see gpu_raster_worker_pool.cc in (Add flag to beginRecording to request saveLayer information - https://codereview.chromium.org/721883002/) for where this is happening in Chromium.
