aarzilli 6ef7aa8743 service: move some type conversions from service/debugger to rpc pkgs
Move the conversion of some 'proc' types from service/debugger into
service/rpc1 and service/rpc2. The methods of
service/debugger.(*Debugger) are also used by service/dap which
requires these types to be converted differently and converting them
twice is inefficent and doesn't make much sense.
