BlinkMemoryMgt: Annotate some classes of Blink's presentation module with USING_FAST_MALLOC

The OnionSoup effort has a goal of allocating all garbage-collectible Blink objects
with Oilpan or PartitionAlloc. However, some classes of
//blink/renderer/modules/presentation have not yet been allocated with them so far.
So their uses of non-garbage-collected objects should be restricted to cases where
the garbage collector can discover their references. The macros of Allocator will be
useful for the non-garbage-collected objects to avoid unintended allocations.

After some analyzes, it was concluded that for the case of PresentationAvailabilityCallbacks,
PresentationAvailabilityState and PresentationConnectionCallbacks classes, they make sense
to use USING_FAST_MALLOC because they have been used as member variables with smart pointers.
