Remove RecordTagHelper, add extraction notices

Per DHH in #18337, ActionView::Helpers::RecordTagHelper has been
extracted to an external gem (source currently lives at
todd/record_tag_helper). Removal notices have also been added for anyone
upgrading that use the extracted methods.

-      #    <%= div_for(@person, class: "foo") do %>

-      # You can also pass an array of Active Record objects, which will then
-      # get iterated over and yield each record as an argument for the block.

-      #
-      #    <%= div_for(@people, class: "foo") do |person| %>

-      #      <td><%= @person.last_name %></td>
-      #    <% end %>

-      #
-      #    <tr id="person_123" class="person">....</tr>

-      #    <%= content_tag_for(:tr, @person, :foo) do %> ...
-      #
-      # produces:
-      #
-      #    <tr id="foo_person_123" class="person">...
-      #
-      # You can also pass an array of objects which this method will loop through
-      # and yield the current object to the supplied block, reducing the need for
-      # having to iterate through the object (using <tt>each</tt>) beforehand.
-      # For example (assuming @people is an array of Person objects):
-      #
-      #    <%= content_tag_for(:tr, @people) do |person| %>
-      #      <td><%= person.first_name %></td>
-      #      <td><%= person.last_name %></td>

-      # content_tag_for also accepts a hash of options, which will be converted to
-      # additional HTML attributes. If you specify a <tt>:class</tt> value, it will be combined
-      # with the default class name for your object. For example:
-      #
-      #    <%= content_tag_for(:li, @person, class: "bar") %>...
