Introduce FullscreenElementStack::RequestType
This replaces flags + FullScreenCheckType, for a few reasons:
1. An UnprefixedRequest will be added, for which neither
ALLOW_KEYBOARD_INPUT nor FullScreenCheckType is possible. Not all
previously possible combinations are possible, either.
2. An enum is clearer than flags at the call site. In particular,
0 was passed to HTMLMediaElement::enterFullscreen() which would
disallow keyboard input, which was not obivous and possibly not
even the original intention. The behavior was preserved but should
probably be changed to allow keyboard input in a future patch.
3. LEGACY_MOZILLA_REQUEST as a public part of Element.h is weird.
