Prevent the user from importing annotations until we have:

 - A group to import into
 - A set of existing annotations to match against
 - Document metadata to use for the new annotations

I considered replacing the whole dialog with a `LoadingSpinner` until these
conditions are met, like the Export dialog does, but it makes for a less jumpy
transition when eg. switching groups if we just disable the button.

Record the fact that imported annotations were created via the client's import
mechanism, and the original ID of the annotation. This is currently stored in
the `extra` field. h supports setting arbitrary fields at the top level of
annotations, so we could have put the data there instead. However using the
`extra` field for custom fields is a convention already used by some API
clients, and is distinct from a standard/validated field if we add one later on.

Fixes https://github.com/hypothesis/client/issues/5738

Speed up large imports by allowing up to 5 imports to be in-flight concurrently.
The simplest approach to this would be to divide the annotations into batches
and save one at a time. However due to the variability in the time that an
individual import can take, this can lead to sub-optimal concurrency. Instead
structure the code so that we try to always keep `MAX_CONCURRENT_IMPORTS`
imports in flight at once, as long as there are that many remaining.

Fixes https://github.com/hypothesis/client/issues/5739

This ensures that the count of annotations displayed in the Export tab matches
the count of top-level annotations that we show in the user list, and actually
import, in the Import tab.

When reporting unsaved annotations, use the term "draft" which covers both
annotations and replies.

Part of https://github.com/hypothesis/client/issues/5742

Simplify test to just check the essential `<details>`-related behavior compared
to other tests.

In the initial implementation of import, we have decided to exclude replies to
simplify the feature. In other words, the import feature only supports importing
top level annotations from a single user.

Extract the reading and parsing of Hypothesis JSON files out of the
ImportAnnotations component and into a separate module. This allows for it to be
more directly tested, and also may help to fix test flakiness in
ImportAnnotations by replacing the file "reading" with a fake that takes a more
deterministic amount of time (one tick).

May fix https://github.com/hypothesis/client/issues/5746.

 - Add `ImportAnnotationsService` service to handle import process for
   annotations and show messages when done.

 - Add `importsPending` store fields to track the number of imports in
   flight.

 - When the `import_annotations` feature flag is enabled, show an Import tab
   in the share dialog.

 - Add `ImportAnnotations` component which implements the UI for the
   Import tab and initiates import when the user clicks "Import"
