d097f430 - [lldb] Fixed the error `unable to launch a GDB server` in API tests (#98833)

[lldb] Fixed the error `unable to launch a GDB server` in API tests (#98833) TestPlatformLaunchGDBServer.py runs `ldb-server` w/o parameters `--min-gdbserver-port`, `--max-gdbserver-port` or `--gdbserver-port`. So `gdbserver_portmap` is empty and `gdbserver_portmap.GetNextAvailablePort()` will return 0. Do not call `portmap_for_child.AllowPort(0)` in this case. Otherwise `portmap_for_child.GetNextAvailablePort()` will allocate and never free the port 0 and next call `portmap_for_child.GetNextAvailablePort()` will fail. Added few asserts in `GDBRemoteCommunicationServerPlatform::PortMap` to avoid such issue in the future. This patch fixes a bug added in #88845. The behaviour is very close to #97537 w/o parameters `--min-gdbserver-port`, `--max-gdbserver-port` and `--gdbserver-port`.
