pdfium: replace FPDFTextObj_GetColor() patch with backport

Upstream already got FPDFPageObj_GetFillColor() and
FPDFPageObj_GetStrokeColor(), so what was necessary is just a
FPDFText_GetTextRenderMode() to find out which one to use.

+Subject: [PATCH] Add FPDFText_GetTextRenderMode() API
+
+This allows deciding if FPDFPageObj_GetFillColor() or
+FPDFPageObj_GetStrokeColor() should be used to get the effective color
+of a text object.
