[UXTHEME] -Implement support for non rectangular caption buttons in WM_NCHITTEST handling. Please note that non rectangular buttons or buttons with no gaps between them are HACKY for XP so hittesting will never work properly (we really mimic windows xp here). Cache the position of caption buttons in the WINDOWINFO. CORE-13171
