sched/clock/ timekeeping: Use clock_basetime() to initialize g_clock_wall_time to get the best initial RTC value and initialize g_clock_last_counter too since the hardware may not start counting from zero.

clock: add clock_resynchronize and use subseconds RTC
...
Add clock_resynchronize for better synchronization of CLOCK_REALTIME and CLOCK_MONOTONIC to match RTC after resume from low-power state.
Add up_rtc_getdatetime_with_subseconds under CONFIG_ARCH_HAVE_RTC_SUBSECONDS to allow initializing (and resynchronizing) system clock with subseconds accuracy RTC.
