layerindex/views: support querying by layer name

Browse Source 
This change supports querying recipes that belong to a specific layer
by using the prefix "layer:" + the desired layer name, for example:
"layer: openembedded-core" and this string can be used by itself or
combined with other supported options.

A descriptive error message is displayed when the query string has an
unexpected formatting or a non-valid layer name is searched.
