Define CBS/CBB tags as uint32_t with a typedef.

We use unsigned, but we actually assume it is 32-bit for the bit-packing
strategy. But also introduce a typedef to hint that callers shouldn't
treat it as an arbitrary 32-bit integer. A typedef would also allow us
to extend to uint64_t in the future, if we ever need to.

Update-Note: Some APIs switch from unsigned * to uint32_t * out
pointers. This is only source-compatible if unsigned and uint32_t are
the exact same type. The CQ suggests this is indeed true. If they are
not, replace unsigned with CBS_ASN1_TAG to fix the build.
