Refactor code into GetJpxDecodeAction().

This moves some JPEG2000 colorspace handling code out of
CPDF_DIBBase::LoadJpxBitmap() and into a standalone function. Instead of
directly manipulating CPDF_DIBBase state, the new GetJpxDecodeAction()
function returns an enum value to tell CPDF_DIBBase what to do.

This will likely make fixing https://crbug.com/1012369 easier, because
the fix will try to handle JPEG2000 vs. PDF colorspace mismatches, and
the code that handles those cases may be needed for multiple conditions.
