Update Skia rendering results of FPDFFormFillEmbedderTest.FormText.

In test FPDFFormFillEmbedderTest.FormText, it uses DrawTextString() to
type "ABC" into the form with option |bClearType| (which enables LCD
optimization). Since CL https://pdfium-review.googlesource.com/69350
enables Skia to take LCD optimization into consideration when rendering
text, the Skia expected results for this test need to be updated
accordingly.
