Subject: [PATCH v2 3/4] c23: Implement newly base for timespec_get
These are implemented https://gustedt.gitlabpages.inria.fr/c23-library/#time_monotonic-time_active-time_thread_active
with:
#define TIME_UTC 1
#define TIME_MONOTONIC 2
#define TIME_ACTIVE 3
#define TIME_THREAD_ACTIVE 4
#define TIME_MONOTONIC_RAW 5
#define TIME_UTC_COARSE 6
#define TIME_MONOTONIC_COARSE 7
#define TIME_BOOTTIME 8
#define TIME_UTC_ALARM 9
#define TIME_BOOTTIME_ALARM 10
#define TIME_SGI_CYCLE 11
#define TIME_TAI 12
