[lldb] Remove lldb-server min and max gdbserver port options

[DavidSpickett]

Since lldb 20, these have had no effect:
https://releases.llvm.org/20.1.0/docs/ReleaseNotes.html#changes-to-lldb

lldb-server now listens to a single port for gdbserver connections and
provides that port to the connection handler processes. This means that
only 2 ports need to be opened in the firewall (one for the lldb-server
platform, one for gdbserver connections). In addition, due to this work,
lldb-server now works on Windows in the server mode.

Remove them.

   wouldn't step into multiple inheritance virtual functions.
