Rémy Oudompheng 711ea1e716 cmd/cgo: simplify and fix handling of untyped constants
Instead of trying to guess type of constants in the AST,
which is hard, use the "var cgo%d Type = Constant"
so that typechecking is left to the Go compiler.

The previous code could still fail in some cases
for constants imported from other modules
or defined in other, non-cgo files.

Fixes #30527
