Digging into several crashing tests revealed that committing
transactions is a fallible operation. Propagating those errors led to
exposing many new errors caused by the IDBRequest implementation
assuming that all successful responses contained a structured clone. The
end result is a bunch of new test failures that were previously hidden.
Testing: Existing test coverage is sufficient.

While this introduces many new crashes in the test results, that's
actually progress. Previously a huge number of tests were failing early
because we never persisted the load-bearing `result` value for
upgradeneeded events, so now we get to see much more interesting
failures in our IndexedDB implementation.
Testing: Existing WPT testsuite for IndexedDB.
Fixes: part of #6963
Depends on #37567.

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
