rtc: optionally return raw time from RTC_Linux_ReadTime*

Browse Source 
For use with RCL_AddSample in the incoming RTC reference clock driver,
we'll want access not to the cooked timestamps, but to the raw ones.

Otherwise, the core reference clock code complains:

  (valid_sample_time) RTC0 refclock sample time 1721242673.092211891
    not valid age=-3.092007

Support both use cases by have the RTC_Linux_ReadTime_* functions take
two nullable pointers, one for cooked and the other for raw time.
