Delete more deprecated code after in-situ uses new diagnostics format (#1041)

* move ascent to new diagnostics

* move Sensei to the new diagnostics

* minor cleaning in new diagnostics

* Delete more deprecated code after in-situ uses new diags

* remove deprecated input options from subcycling test

* Finish updating the doc for Sensei and Ascent with the new diags

-In-situ visualization
-^^^^^^^^^^^^^^^^^^^^^

-Besides the diagnostics described above, WarpX has in-situ visualization capabilities.
-This is controlled by the following option(s):
-
-* ``insitu.int`` (`integer`; 0 by default)
-    Turns in situ processing on or off and controls how often data is processed.
-
-* ``insitu.start`` (`integer`; 0 by default)
-    Controls when in situ processing starts.
-
-* ``insitu.config`` (`string`)
-    Points to the SENSEI XML file which selects and configures the desired back end.
-
-* ``insitu.pin_mesh`` (`integer`; 0 by default)
-    when 1 lower left corner of the mesh is pinned to 0.,0.,0.
