CCA: Render the first page of PDF to an image as the thumbnail

The previous PDF image extraction logic is error-prone and hard to
maintain. This CL renders the first page of PDF to an image instead of
extracting the first image in the PDF as the thumbnail.

Bug: 330084715, 329069826
Test: Gallery button can display PDFs from CCA and other sources correctly
