bitbake: toaster: All machines Add filtering based on layer in project

Add a filter so that we can filter machines which are already being provided
by a layer in the current project.
Also make sure that we're only showing layers which are compatible with
the current project.
Also handle no results returned and page heading reflecting the number of
results returned from a search.

AlexD solved conflicts while merging the patch.
