Currently, when debugging a program with `lldb-dap` on Windows and using
the `integratedTerminal` option, lldb-dap immediatly stops with an
`0x80000003` Exception. This is because `ntdll` executes an `int3`
breakpoint during process initialization when a debugger is attached.
This patch makes `lldb` and `lldb-server` skip the first `int3` after
launch when it originates from a system module (the loader's debugger
notification). Only that first loader breakpoint is skipped. Any later
int3, including `__debugbreak()`, `__builtin_debugtrap()` in the
debuggee's own code, still stops the debugger.
