LOG: [lldb] Gate `PolicyStack::Current()` log behind verbose (#209527)

`Process::GetState()` calls `PolicyStack::Get().Current()` on every
prompt redraw, so the previous unconditional LLDB_LOG at the read site
fired on every keypress once `log enable lldb process` was on, drowning
out any other process log output. Keep the dump for when it's actually
wanted, but only fire it if the log is set to verbose.
