Update wxMemoryInputStream::Peek to set last read count.

Browse source 
This aligns the memory stream's Peek with other streams' Peek impls by
making it set the last read count to 1 when it successfully peeks a
character, or 0 when it does not. While the formal docs do not link
Peek to LastCount directly, the in-source comments on the declaration
of both wxInputStream::Peek and wxInputStream::LastRead both indicate
that Peek will set the last read count.
