Use CheckedNumerics to calculate size in CalculatePitchAndSize().

In CFX_DIBitmap::CalculatePitchAndSize(), instead of manually avoiding
integer overflow when calculating the pitch, use CheckedNumerics instead
by instantiating a FX_SAFE_UINT32.

This raises the limit for the maximum possible size.
