Set Grpc server-side maximum message size

Set the Grpc server maximum receive message size to accommodate
for the unbounded "CaptureOptions" message which can be bigger
than the default 4'194'304 maximum size.

Tests: select thousands of function to instrument and start a capture.
Before the change, we would get a popup with a message size error.
