win32: simplify the clock selection on startup

No need to do a fake call to vlc_threads_setup() every time the vlc_tick_now() is called early.

mdate_wall provides a wall clock that can be used without initialization.

Plus some misc code cleaning of clock/thread related code.

changed milestone to %4.0

added Component::Core label

added MRStatus::Reviewable label

BTW, calling vlc_threads_setup(NULL) is broken. It will call var_InheritBool(vlc, "high-priority") with a NULL vlc. That's the reason why I tried to avoid this call.

added MRStatus::InReview label and removed MRStatus::Reviewable label
