CharacterMap: Use binary searches rather than linear lookups where possible.
UnicodeBlockView::SelectBlockForCharacter and CharacterView::_FrameFor
use the same linear search to find which block a character is in, so I
refactored both to use a shared BlockForCharacter function in UnicodeBlocks.cpp
that is a binary search. CharacterView::_BlockAt also had a TODO comment to
use a binary search, so I rewrote it as a binary search. It's not the same
search as the aforementioned BlockForCharacter function. These two changes
ought to improve the overall performance of CharacterMap.
