  [lldb] Fix lldb-server host and port address parsing (#191414)

This patch fixes 2 problems in lldb-server argument parser:

1. Let's try to start lldb-server with incorrect arguments

```
./lldb-server platform --listen *:1111--server
```
Current behavior
 * lldb-server run in gdbserver mode with port 1111

Expected behavior
 * fail, as `1111–server` is not a number

2. And try to start lldb-server with host:port specification without
colon
```
./lldb-server gdbserver 1111 ./test 
Launched './test' as process 186...

We expect to see an error instead of lldb-server crash in this case
