Create set request speed base action function

This action function is intended to allow the base request speed to be
set to the max value from a group of properties. The base request speed
is the base speed used in requesting a new target speed. By default, the
base request speed is the current target speed.

For example, this action can be used to set the base request speed used
in calculating a new target speed to be based on the max tach feedback
speed from a group of fans instead of the current target speed.

Adding this action function requires the other non-template functions to
also be slightly modified due to linker errors.
