grunt: Use higher priority TCPC interrupt tasks.
See also go/usb-pd-slow-response-time. Lift tcpc_alert_event interrupt
handler to baseboard.c to reduce duplication.
BUG=b:112848644, b:111909282
BRANCH=none
TEST=Observe response time after SrcCap to Sink Request is 15ms on
Careena and Grunt hardware after forcing a sysjump. Repeat test on
Careena Port 0 with the DB disconnected (containing Port 1), also 15ms.
