UPSTREAM: commonlib: Add timestamp IDs for Chrome OS hypervisor

Chrome OS is experimenting with a hypervisor layer that boots after
firmware, but before the OS. From the OS' perspective, it can be
considered an extension of firmware, and hence it makes sense to emit
timestamp to track hypervisor boot latency. This change adds
timestamp IDs in the 1200-1300 range for this purpose.

BUG=b:217638034
BRANCH=none
TEST=Manual: cbmem -a TS_CRHV_BOOT to add a timestamp, cbmem -t to
verify that it got added to the timestamp table.
