New methods for input_select component (#42968)

Browse source 
This adds a `cycle` attribute to select_previous/next, and
select_first and select_last services.

This is quite useful for streamlining using input_select via
automations, such as when they represent a list of states to step
through; if the first option is the dimmest and the last the brightest,
one may not want to accidentally cycle from the first to the last, for
example.

Similarly, being able to directly select the first or last removes
adjustment in related automations.
