Prepare field watchpoint support
Adds field read/write events in the instrumentation. The debugger now registers
as a listener for these events so JDWP field access and field modification
events can be reported.
This CL will be followed by another one to report these events from the
interpreter. Therefore no JDWP field access and field modification events
can be sent for now.
