[Telemetry] Remove actions in RunPageInteractions for some of page_cycler's pages.

[Telemetry] Remove actions in RunPageInteractions for some of page_cycler's pages.

This is needed so that page_cycler's action_name_to_run's
field can later be changed from empty string to
'RunPageInteractions'.

To reviewers: pages that have RunPageInteractions removed
will be using the default implementation which does
nothing. Those pages are only used by the page_cycler
benchmark.
