ed9a79f3f4
Adds indexeddb support to servo. At the moment heed is being used as the backend, although this can be swapped out by implementing `KvsEngine`. This PR adds a thread + a thread pool for Indexeddb related operations. Also `database_access_task_source` is added for Indexeddb related operations. This is a partial rewrite of #25214. (Reopened due to branching issue) Fixes #6963 --------- Signed-off-by: Ashwin Naren <arihant2math@gmail.com> Signed-off-by: Josh Matthews <josh@joshmatthews.net> Co-authored-by: Rasmus Viitanen <rasviitanen@gmail.com> Co-authored-by: Josh Matthews <josh@joshmatthews.net>
