this symbol gives you access to the true internal PluginBuild object that was used for constructing a SuperPluginBuild.
it can be used as a means to check whether you're inside super-build or not,
or if you have a situation where it is necessary for super-build to be bypassed,
such as in the case of EsbuildNativeResolver, which is spawned by nativeReplicaPluginSetup.
