Inline Podcast Bookmarks tab

[bjtitus]

Fixes PCIOS-126

Moves the Bookmarks view inside the Podcast page inside of the tab.

• The BookmarksListView is embedded inside of a cell within the PodcastViewController table view. I felt that this was a compromise between keeping the functionality and style of the other bookmarks screens and avoiding a larger refactor of the PodcastViewController. It could use it at some point but I don't know that this is the time.
• The multi-select action bar logic was moved into ActionBarOverlayView and ActionBarView so it could be both used in the BookmarksListView and presented directly (and properly sized and positioned) on PodcastViewController. Since BookmarksListView is being used as a cell and can flow offscreen, the positioning isn't easily possible strictly in SwiftUI.

Notes

I took a look at updating some of the styling to better match the Episodes tab but I think that can be a follow up to this PR to keep the size on the smaller side. I focused on maintaining complete functionality and trying to make things operate smoothly rather than making any changes to the existing design.

To test

• Enable the podcastBookmarksInline Feature Flag - I've left it disabled for now as I'm not sure when this will ship and I'd like to have designers take a look first as we may want to unify a few details before launch
• Use a plus account or enable Paid Plus in the Developer menu
• Navigate to a Podcast page
• Tap the "Bookmarks" tab
• ✅ Ensure the Empty view shows up and works as expected
• Add bookmarks to a podcast, some with titles
• Check the bookmarks
• ✅ Ensure the bookmarks appear
• Search your bookmarks
• ✅ Ensure they filter as expected
• Try selecting podcasts by long tapping and using the various selection options
• Try editing and deleting bookmarks

Checklist

• I have considered if this change warrants user-facing release notes and have added them to CHANGELOG.md if necessary.
• I have considered adding unit tests for my changes.
• I have updated (or requested that someone edit) the spreadsheet to reflect any new or changed analytics.

I was testing the bookmarks multi-select actions and it looks they are not being triggered.
