add sponsoredCount-prop

[hiagolcm]

What problem is this solving?

Currently, the maximum number of sponsoredProducts is hardcoded. This PR allows the developer to change it via store-theme. For example:

"store.search": {
    "blocks": ["search-result-layout"],
    "props": {
      "context": {
        "sponsoredCount": 4
      }
    }
  },

It also removes the sponsoredProductsBehavior which is a deprecated prop.

How to test it?
