Backport AST changes to Ppat_unpack (#2774)
* parser-std: Backport Ppat_unpack
Also backport the `map_loc` change in `Ast_mapper`.
* parser-ext: Backport Ppat_unpack
We already did a similar change in the past, the parsetree doesn't
change.
* parser-ext: Backport Ast_mapper map_loc changes
* Disable rewriting rule for Ppat_unpack
It is no longer valid to rewrite:
((module M) : (module S))
into:
(module M : S)
