Create new "platform process connect" command

The standard remote debugging workflow with gdb is to start the
application on the remote host under gdbserver (e.g.: gdbserver :5039
a.out) and then connect to it with gdb.

The same workflow is supported by debugserver/lldb-gdbserver with a very
similar syntax but to access all features of lldb we need to be
connected also to an lldb-platform instance running on the target.

Before this change this had to be done manually with starting a separate
lldb-platform on the target machine and then connecting to it with lldb
before connecting to the process.

This change add a new command to lldb called "lldb platform connect"
what makes it possible to connect to a platform and a process instance
with a single command with specifying only a single connection port.
With this command replacing gdbserver in a gdb based worflow is usually
as simple as replacing the command to execute gdbserver with executing
lldb-platform.

Example for the new workflow:
* On the target:
  lldb-server platform --listen localhost:5432 -- a.out arg1 arg2
* On the host:
  (lldb) platform select remote-android
  (lldb) platform process connect connect://localhost:5432
