[yocto] [layerindex-web][PATCH] views: support querying by layer name

[Jose Lamego]

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.
