[Search] [Playground] Adding playground locators (#190606)

Adds locators for the playground app in the enterprise search and search
playground plugins.
These will be used by the file upload tool to link to Playground after a
successful upload. https://github.com/elastic/kibana/pull/186956
These locators are not registered in the observability or security
serverless projects, and so the file upload plugin will not render the
link to Playground.

Note to reviewers, I originally attempted to have one common locator
class which would be used by both plugins, this turned out to be more
trouble due to cross plugin import restrictions, plus I was concerned
the increase to the enterprise search bundle would be larger than the
size of the duplicated function.
