Add "src:" prefix to search by source ID (mihonapp/mihon#2927)

Allows users to search for the exact source ID in their library.

Similar to the Browse > Migrate screen, but filtered in the Library,
where users can take all the usual actions.

Could be used in the future to change the search behaviour of tapping
the source name in the title info view to search by the ID with this
prefix.

(cherry picked from commit 4e4bdffdf38043418685ab42b177c8476842c83c)
