enable gdbserver debug in c/c++ source

[1637664504]

Request:

// same as gdbserver, wait gdb remote connect debug.
int main()
{
gdb_init(1234);


// stop
gdb_end();
}

Some time,

1. manual command launch program not inconvenient;
2. --attach pid also not inconvenient;

I want enable gdbserver debug in source by c/c++ API.

You could do it by system: https://github.com/vadimcn/codelldb/blob/master/MANUAL.md#attaching-debugger-to-the-current-process-c
Centainly, providing an API is better, but I don't have time to do it. You can try it and send a PR!
