gdb: Fix Windows build after #include shuffle

Without this patch, the build chokes on:

    ../../src/gdb/windows-nat.c:384:21: error: field 'm_debug_event_pending' has incomplete type 'std::atomic<bool>'
      384 |   std::atomic<bool> m_debug_event_pending { false };

Presumably windows-nat.c relied on objfiles.h including <atomic>,
which was undone in 2024-05-16 "gdb: remove unused includes in
objfiles.{c,h}" (f617661c110).
