ivi-homescreen: improve AGL integration
Changes: - For now add local patches for three changes that Marius has submitted upstream that fix issues with respect to running as a normal application against agl-compositor and configuration via the JSON configuration file. The first of these patches has been merged upstream, but bumping the level of meta-flutter to get it brings other rework that it seems perhaps better to wait on a tagged upstream release for. - Add another patch to add a '--app-id' command-line option to the embedder. This avoids needing to use a JSON configuration file for simple (i.e. non-homescreen) applications when running multiple apps against agl-compositor. The use of the example JSON file for the ivi-homescreen recipe itself has been left alone for now since it provides a reference for doing so. - Rename the embedder binary from "homescreen" to "flutter" to avoid collision with the existing Qt homescreen application in meta-agl-demo. This allows integrating Flutter applications into images using the Qt homescreen for testing in the period while a Flutter replacement is worked on. Discussion about possibly renaming the embedder to something more generic along these lines has started with upstream. - Split the embedder binary into a separate package from the ivi-homescreen package that contains the systemd unit file. We do not want the "homescreen" systemd unit when using the embedder in other images that use applaunchd, so this split seems the most straightforward way to avoid pulling it in. - Remove installing the "homescreen" system level systemd unit, as it does not get used in agl-image-flutter (it is installed as a user unit instead).

+Subject: [PATCH 1/3] Allow the embedder to run as a regular/normal application
+ (#71)
+
+* shell: Do not issue always the ready request
+
+Rather than sending the ready request always, just do it when we've
+found at least a background type of surface.
+
+This way we can have a flutter instance as a regular application but
+also as a shell client.
+
+This is a work-around for the time being, a much more suitable approach
+would be to have a mechanism that tells us when the client has finished
+loading or has it's first frame swapped (or something similar to that).
+
+Note that we need at least a background surface so not finding one
+assumes that we're a regular application (WINDOW_NORMAL).
+

+
+* shell: Do not attempt always bind to agl-shell interface
+
+This helps up running as a regular application in
+situations where we already have a client bound to the agl-shell
+interface.
+
+We can't really accept more than one client to bind to the interface and
+without a change in the protocol to avoid racy situations, it seems more
+natural for the embedder to infer if it actually needs to do that.
+
+When the protocol has been updated to include additional events to let
+clients that they've lost the race, we can remove this change.
