'm_headerOffset + m_infoHeader.biSize' is used often in BMPImageReader.cpp.
It is even recalulated several time in a same function. This patch cleans up
this kind of repeated code.

* Source/WebCore/platform/image-decoders/bmp/BMPImageReader.cpp:
(BMPImageReader::BMPImageReader):
(BMPImageReader::decodeBMP):
(BMPImageReader::readInfoHeaderSize):
(BMPImageReader::processBitmasks):
(BMPImageReader::processColorTable):
* Source/WebCore/platform/image-decoders/bmp/BMPImageReader.h: Remove 'm_tableSizeInBytes'
