Address wake from sleep instability (#11450)

Browse source 
* resolve race condition between suspend and wake in LUFA

* avoid multiple calls to suspend_power_down() / suspend_wakeup_init()

* Remove duplicate suspend_power_down_kb() call

* pause on wakeup to wait for USB state to settle

* need the repeated suspend_power_down() (that's where the sleep is)

* more efficient implementation

* fine tune the pause after sending wakeup

* speculative chibios version of pause-after-wake

* make wakeup delay configurable, and adjust value

* better location for wakeup delay
