Add whitelist flag for --incompatible_disallow_legacy_javainfo.

Progress on #5821

RELNOTES: There is a new flag available `--experimental_java_common_create_provider_enabled_packages` that acts as a whitelist for usages of `java_common.create_provider`. The constructor will be deprecated in Bazel 0.23.
