feat: provisionally support V2 libraries in LibraryContentBlock (randomized only) (#33263)

Browse Source 
Refactors and reworks the LibraryContentBlock so that its
sync-from-library operations are asynchronous and work with
V2 content libraries. This also required us to make
library_content block duplication asynchronous, as that
involves syncing from the source library.

For the sake of clarity, this PR includes two major method renames:

* update_children(...) -> sync_from_library(...)
* refresh_library(...) -> sync_from_library(upgrade_to_latest=True, ...)

an an XBlock HTTP handler rename:

  /refresh_children -> /upgrade_and_sync

There are still a couple issues with import or duplication
of library_content blocks referencing V2 libraries other than
latest. These will be resolved in an upcoming PR.
