Restrict SdkMemberTypes that can be used with sdk/sdk_snapshot

By default SdkMemberTypes are only supported on module_exports module
type. Support for sdk module type has to be explicitly specified.

The java_header_libs, native_shared_libs and stubs_sources are
supported on sdk. The latter is required to provide the stubs source
for an API specified in java_header_libs as they should be kept in
sync.
