[interp] [ast] Make raw_cases_pattern_expr private.

The type `raw_cases_pattern_expr` is used only in the interpretation
of notation patterns. Indeed, this should be a private type thus we
make it local to `Constrintern`; it makes no sense to expose it in the
public AST.

The patch is routine, except for the case used to interpret primitives
in patterns. We now return a `glob_constr` representing the raw
pattern, instead of the private raw pattern type. This could be
further refactored but have opted to be conservative here.

This patch is a refinement of b2953849b999d1c3b42c0f494b234f2a93ac7754
, see the commentaries there for more information about
`raw_cases_pattern_expr`.
