Change ClassStatus to fit into 4 bits.

In preparation for extending the type check bit string from
24 to 28 bits, rewrite ClassStatus to fit into 4 bits. Also
perform a proper cleanup of the ClassStatus, i.e. change it
to an enum class, remove the "Status" word from enumerator
names, replace "Max" with "Last" in line with other
enumerations and remove aliases from mirror::Class.
