Joe McGill d6bec79fe7 Media: Keep PDF previews from overwriting files.
Since support for PDF previews were added in [38949], it's possible
that the generated image file could overwrite an existing image file
with the same name. This uses `wp_unique_filename()` to avoid this
issue and adds a '-pdf' identifier on the end of filenames.

Fixes #39875. See #31050.
