[lldb] Remove lldb-server min and max gdbserver port options (#133275)

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.
