kern: Add a mach host operation which returns elapsed time since bootup
Add host_get_uptime64() mach interface operation. It can be used to get
the time passed since the boot up.
* doc/mach.texi: Add the documentation for the operation
* include/mach/mach_host.defs: Add the interface
* include/mach/time_value.h: Extend the mappable time variable
* kern/mach_clock.c: Operation implementation
* kern/mach_clock.h: Add a new variable for storing uptime
