Fix ARM's genPutArgStk codegen (#23867)
* Fix ARM's genPutArgStk codegen
When the OBJ node wraps a LCL_VAR node the code uses the type information (struct size, GC layout) from LclVarDsc. This is not always correct because the OBJ may actually have a different struct type due to type reinterpretation (e.g. Unsafe.As<X, Y>).
