Files: Do not show "Available Transforms" when none are supported
Summary:
Showing "Available Transforms" for files which cannot have transforms is useless and slightly misleading until you spot the "Supported" table column.
Instead just do not list transforms which are not supported for this file type.
Closes T16260
Test Plan:
* Upload an iamge file, a movie file, a text file.
* Go to their corresponding file page and select "View Transforms".
* Look at the "Available Transforms" table before and after applying this patch.
