`VarHandles.getStaticFieldFromBaseAndOffset` maps a base/offset/fieldType to a static `Field`. It's fragile to assume that the location of a static field returned by `Unsafe.staticFieldBase` is a Class object. This changes the VarHandle implementation for static fields (i.e. `FieldStaticReadOnly` and `FieldStaticReadWrite` classes) to include the receiver type in addition to the base and offset.
