Zone Equipment array is not always initialized (causes exception/crash)

[tanaya-mankad]

Issue overview

The zone equipment array (state.dataZoneEquip->ZoneEquipConfig) is not consistently initialized before its use.
Paths through the code that calculate internal heat gains, for example, initialize zone equipment there, so subsequent iterations over zone equipment in other classes such as VRF "accidentally" work. When internal heat gains (e.g. lights) are omitted from such VRF-containing models, the array is unsized and throws an exception.
