usb_charger: support processing events synchronously
Some hardware topologies require that high-priority tasks be able to
process BC1.2 interrupts at higher priority than the BC1.2 task runs at,
but increasing the priority of the BC1.2 task may not be appropriate.
This adds a synchronous version of usb_charger_task_set_event suitable
for those devices' needs.
BUG=b:269064073
TEST=Nissa devices using the new function on shared USB-C IRQs no longer
experience priority inversion that sometimes causes incorrect
behavior.
BRANCH=nissa
