[kernel] Timestamps option for signaled objects

This patch enhances zx_object_wait_async() to optionally
tell the consumer the monotonic time when the object was
signaled by a new options flag ZX_WAIT_ASYNC_TIMESTAMP

The zx_packet_signal_t is therefore enhanced to contain
a timestamp member which replaces an existing reserved0
member.

TEST: new core-test added.
