Kernel: Modify TimeManagement::current_time(..) API so it can't fail. (#6869)

Browse source 
The fact that current_time can "fail" makes its use a bit awkward.
All callers in the Kernel are trusted besides syscalls, so assert
that they never get there, and make sure all current callers perform
validation of the clock_id with TimeManagement::is_valid_clock_id().

I have fuzzed this change locally for a bit to make sure I didn't
miss any obvious regression.
