Add selector syntax to index expressions (#118614)

This PR introduces a new syntactical feature to index expression resolution: The selector.

Selectors, denoted with a :: followed by a recognized suffix will allow users to specify which component of 
an index abstraction they would like to operate on within an API call. In this case, an index abstraction is a 
concrete index, data stream, or alias; Any abstraction that can be resolved to a set of indices/shards. We 
define a component of an index abstraction to be some searchable unit of the index abstraction.
