[kernel][timers] Introduce ZX_CLOCK_BOOT for timers and clocks

Introduces the ZX_CLOCK_BOOT clock_id and have kernel timers use it
internally. Note that this change does not expose boot timers to
userspace. It just adds the new clock_id, which replaces the usage of
the Timer::ReferenceTimeline enum. This will make the introduction of
the boot timeline to TimerDispatcher a bit cleaner.

This change also uses the new ZX_CLOCK_BOOT constant to create
time_boot, which is an alias of basic_time<ZX_CLOCK_BOOT>. This stronger
type then allows us to create a libzx wrapper for zx_clock_get_boot.
