[PATCH v3 0/1] MR8916: ntdll: Switch to CLOCK_BOOTTIME for monotonic counters on Linux.

[Marc-Aurel Zent (＠mzent)]

This now accounts for system suspend periods on Linux, similar to how native win32 ticks work.

On macOS `mach_continuous_time` already does so.

~~On BSDs (and other POSIX compliant operating systems) `CLOCK_MONOTONIC` likewise includes suspend time. However they also provide a `CLOCK_BOOTTIME`, which does *not* include suspend time, hence the added `__linux__` check there.~~
