Contributions summary:Yi contributed to the CoreRT runtime project by implementing features related to preinitialized data and frozen arrays. They introduced the `PreInitFieldInfo`, `FrozenArrayNode`, and `GCStaticsPreInitDataNode` classes to handle the pre-initialization of static fields and array data. Furthermore, they modified existing code, including the `GCStaticsNode` and `StartupCodeHelper`, to accommodate and utilize the preinitialized data. They also added a new test for preinit data and made some updates to enable writing repro in IL.
