Merge to M47: Change |CCodec_ScanlineDecoder::m_Pitch| to FX_DWORD

This matches the type of the corresponding |CFX_DIBSource::m_Pitch|,
where integer overflow is checked for FX_DWORD. This change is
propagated to many other places.

Also, check for integer overflow in |CCodec_RLScanlineDecoder::Create|
during the calculation of |m_Pitch| since it aligns to 4 bytes while
overflow was was previously checked without this alignment.
