Make Servo_NoteExplicitHints allow multiple animation restyle hints, including SMIL
Make Servo_NoteExplicitHints allow multiple animation restyle hints, including SMIL

The existing code here appears to be wrong since we should allow *both*
animation and transition restyles to appear at the same time. This patch
fixes the assertion and subsequent check and also extends it to support
all animation restyle hints, including SMIL.
