Implement handling of `library:` keys in thread stop replies.

Summary

When a windows remote stops because of a DLL load/unload, the debug server
sends a stop reply packet that contains a library key with any value (usually
just library:1). This indicates to the debugger that a library has been
loaded or unloaded and that the list of libraries should be refreshed (usually
with qXfer:libraries:read).

This change just triggers a call to LoadModules() which in turns will send a
remote library read command when a stop reply that requests it is received.

I leave this review to the others as I have no idea about how library loading works on Windows. (On Linux/Android we use a breakpoint on a special symbol exposed by the linker)
