Create FPDF_Thumbnail API and refactor raw stream retrieval

FPDF_Thumbnail API contains:
  - FPDFPage_GetRawThumbnailDataFromPage()
  - FPDFPage_GetDecodedThumbnailDataFromPage()
  - FPDFPage_GetThumbnailAsBitmapFromPage()

These allow getting the stream data for a thumbnail from a
page and also retrieving a thumbnail as a bitmap. Also adds
three new commands to pdfium_test:
  --save-thumbs
  --save-thumbs-dec
  --save-thumbs-raw
