[vm/kernel/bytecode] Revise access to instance fields in bytecode

Constant pool:

* Field constant pool entry is renamed to StaticField
* FieldOffset constant pool entry is replaced with InstanceField.
  InstanceField occupies 2 slots for field offset and field object.
* ContextOffset constant pool entry is removed.
* TypeArgumentsFieldOffset is renamed to TypeArgumentsField

Bytecodes:

* LoadFieldTOS and StoreFieldTOS require InstanceField entry.
* New bytecodes added: LoadContextParent, StoreContextParent,
  LoadContextVar, StoreContextVar, LoadTypeArgumentsField.

This CL is a preparation for compilation of bytecodes related
to instance field accesses.
