metadata: Introduce `EsSub8` and `EsSub32` tags.

They replace the existing `EsEnumVid`, `EsVecLen` and `EsMapLen`
tags altogether; the meaning of them can be easily inferred
from the enclosing tag. It also has an added benefit of
encodings for smaller variant ids or lengths being more compact
(5 bytes to 2 bytes).
