Fonts: Fixed CalcTextSize() width rounding so it behaves more like a ceil. (#3776)

Browse Source 
his is in order for text wrapping to have enough space when provided width precisely calculated with CalcTextSize().x. Amend 7b0bf230.
Note that the rounding of either positions and widths are technically undesirable (e.g. #3437, #791) but variety of code is currently on it so we are first fixing current behavior before we'll eventually change it.

other than compiling misc/freetype/imgui_freetype.cpp and linking with FreeType.
- Use '#define IMGUI_ENABLE_STB_TRUETYPE' if you somehow need the stb_truetype rasterizer to be
compiled in along with the FreeType one, otherwise it is enabled by default.

Would lead to a buffer read overflow.
