[Feature Request] Add a "Clear" Button for Recently Seen Galleries

[Henry8192]

Description

Currently, there's no way to clear "Recently Seen" suggestions in the search view.

Possible Implementation:

In EhPanda/View/Search/SearchRootView.swift:
Add a removeAction property in HistoryGalleriesSection, similar to HistoryKeywordsSection.

In EhPanda/View/Search/SearchRootReducer.swift:
Add a removeHistoryGallery similar to removeHistoryKeyword.

In EhPanda/View/Search/SearchView.swift:
Maybe a "clear" button here?
