StackTraceHandler: call the debugger directly, instead of via /bin/sh

This removes one middle-man and a 512-byte variable in favor of a simple
32-bit enum. This was done in a way so we can extend to use either gdb
or lldb in any OS.

I've renamed the debuggerPresent() function to make its meaning clearer.

Pick-to: 6.3
