Podcast search capabilities

A changelog fragment (cf https://docs.funkwhale.audio/contributing.html#changelog-management)
This MR adds new functionality to search for podcasts on a dedicated podcast screen (a basic copy of the artist vue with a few tweaks to filter out music).
It also adds a direct link to the search page and adds podcasts/series to the search interface to allow users to clearly differentiate between music and podcast content when searching.
