Make WPT tests validating layers with options tentative
The beginLayer's BeginLayerOption parameter was removed from the
canvas layer PR at whatwg/html#9537. We might
pursue this as a followup. In the meantime, the tests validating
BeginLayerOptions should be marked as tentative.
To prevent losing test coverage, this CL adds test variants
using context filters in addition to layer filters.
