time: Import time_after64() and friends from Linux

When using us times it makes sense to use 64bit variables for storage.
The currently implemented time_after() and friends functions only handle
32bit variables. This patch now includes the 64bit variants as well
from Linux. This will be used by the upcoming generic cyclic function
infrastructure.

These macros were copied from include/linux/jiffies.h of Linux 5.18.
