bitbake: toaster: show progress of recipe parsing in recent builds area

Modify buildinfohelper and toasterui so that they record the
recipe parse progress (from ParseProgress events in bitbake)
on the Build object.

Note that because the Build object is now created at the
point when ParseStarted occurs, it is necessary to set the
build name to the empty string initially (hence the migration).
The build name can be set when the build properly starts,
i.e. at the BuildStarted event.

Then use this additional data to determine whether a Build
is in a "Parsing" state, and report this in the JSON API.
This enables the most recent builds area to show the recipe
parse progress.

Add additional logic to update the progress bar if the progress
for a build object changes.

[YOCTO #9631]
