Jonathan Bennett 1d219a93ab Move input init to an init function in InputBroker (#9463) 
* Move input init to an init function in iInputBroker

* Unbreak targets with EXCLUDE_INPUTBROKER

* Update src/input/InputBroker.cpp

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* Fix conditional compilation for input broker

* Apply suggestions from code review

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* Trunk
