Expand storage field names in index specification values

      The values for index specification options, for example partial_filter_expression, could contain field names. Mongoid permits a user to specify that a field in their model should be stored as another field on the server(https://www.mongodb.com/docs/mongoid/master/reference/fields/#specifying-storage-field-names); this expansion is not currently performed for index specification option values but it should be.

      ------

      Original report:

      Tested on Mongoid 7.4.0

      A partial_filter_expression with an aliased field does not work.

      class Person
  include Mongoid::Document
  field :n, as: :name, type: String

  # BROKEN
  index({ name: 1 }, { partial_filter_expression: { name: { '$exists' => true } } })

  # works correctly
  index({ name: 1 }, { partial_filter_expression: { n: { '$exists' => true } } })
end
