Merge to XFA: Fix blank page issue caused by too strict correction on bpc
For bit per component (bpc), PDF spec mentions that a RunLengthDecode or
DCTDecode filter shall always deliver 8-bit samples. However, some PDF files
don't follow this rule. We can find that filter is RunLengthDecode but bpc is
1 in the provided test file. In this case, pdfium will correct bpc to 8 but
the actual bpc is 1. It causes a failure because the data is much more than
the expected. To handle this case, pdfium doesn't correct bpc to 8 when the
original bpc is 1.
