Consider reserving space for one pointer in m
This way setting an input value for example won't incur an allocation here when a range gets created for the selection, and we won't be growing the slot by too much. We still have the static asserts in FragmentOrElement.cpp imposing a maximum size on our slots.
This helps avoid allocations for the first mutation observer (for example, Range) created by a caller.

(The macros in nsTObserverArray.h are copied from similar macros adjacent to them, just changing the array type used in them.)
