[issue45355] Use sizeof(_Py_CODEUNIT) instead of literal 2 for the size of the code unit

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Some C code in 3.10+ uses literal 2 for the size of the code unit. It should use sizeof(_Py_CODEUNIT) instead.

1. It is self-documented and allows to distinguish this 2 from other 2 constants.
2. It will help if we change from 16-bit code units to 24-, 32- or 64-bit code units.
