Stop hardcoding sdk/module_exports dynamic prop types for Bazel overlay.

These sdk/sdk_snapshot/module_exports/module_exports_snapshot properties
are dynamically created using RegisterSdkMemberType [1] and eventually
createDynamicSdkMemberType [2]. All dynamically created sdk member types
are string list types.

Instead of hardcoding the mapping, retrieve them from the registry
instead.
