STM32 device marking Technical note

Nice; however, these marking schemes tend to change over time and with changing packaging sites. I wonder how long will it take the new QR-style marking to propagate into this document... :)

[EDIT] TN1433 has seen rev.7 in Dec.2025, and now displays the new QR style marking.
