gdbserver: finish turning the target ops vector into a class

Now that 'process_stratum_target' has a single field left, namely 'pt'
of type 'process_target', and that all the requests to a
'process_stratum_target' are forwarded to 'pt', meld the
'process_target' class into 'process_stratum_target'.

This essentially means

1. All the references of the form 'the_target->pt' become 'the_target'.

2. All the uses of the name 'process_target' become
   'process_stratum_target'.

3. The platform-specific target op vectors (e.g. linux_target_ops) are
   removed and instances of their "process target" classes are used
   instead.
