[VM] Use the incremental compiler to compile sources only when the observatory
server is started.

When the incremental compiler is used it accumulates state that
increases the footprint of the process. This state is needed only
when the 'reload' or 'expression evaluation' functionality is used
in the debugger.

Currently in the VM we do not have a good way of detecting when the
debugger will be used as the vm service observatory functionality
can be turned on dynamically after the program has started.

This CL turns on the incremental compiler only when command line options
are used to start the observatory server. We could run into issues with
'expression evaluation' when the observatory is started dynamically after
the program is loaded.
