[FuzzMutate] Avoid calling function with metadata/token parameter/return type for `InsertFunctionStrategy`

When there is a function with metadata/token parameter/return type, `InsertFunctionStrategy` will crash.

This patch fixes the problem by falling back to create function declaration when the sampled function contains metadata/token parameter/return type.
