[local_auth] Fix callback thread handling (flutter#3778)

Ensure that all auth replies, which are sent on an internal framework queue per documentation, are dispatched back to the main thread for handling, as all resulting operations (method channel callbacks, display of UI) are things that must be done on the main thread

In order to test this, sets up local_auth with XCTest-based tests, and adds the ability to inject a mock LAContext. (This does not do full unit test backfill, to limit the scope of the PR.)

Fixes flutter/flutter#47465

[local_auth] Update Jetpack dependencies (flutter#3786)

The plugin was still using several beta version of Jetpack libraries
from 2 years ago. Updates to the latest stable version of each.

Fixes flutter/flutter#52742

[video_player]Update README.me (flutter#3713)

[google_maps_flutter_web] Migrate to null-safety. (flutter#3726)

* Updates JS-interop package to google_maps ^5.1.0
* Breaking changes:
  * The property `icon` of a `Marker` cannot be `null`. Defaults to `BitmapDescriptor.defaultMarker`
  * The property `initialCameraPosition` of a `GoogleMapController` can't be `null`. It is also marked as `required`.
  * The parameter `creationId` of the `buildView` method cannot be `null` (this should be handled internally for users of the plugin)
  * Most of the Controller methods can't be called after `remove`/`dispose`. Calling these methods now will throw an Assertion error. Before it'd be a no-op, or a null-pointer exception.

[google_maps_flutter] Fix TileOverlay cloning (flutter#3771)

TileOverlay was not copying its TileProvider. During the NNBD migration,
map object updates were refactored to share code, and in that
refactoring TileOverlay update construction was aligned with other map
objects to use clones, so certain operations involving TileOverlays
started dropping the TileProvider.

Fixes flutter/flutter#77500

[video_player] add http headers (flutter#3671)
