fix(lib): fix MISRA 12.2 violations for BIT32 and BIT64 macros

MISRA interprets all unsigned integer literals as UTLR, which has the
lowest rank required to represent a value. In this specific case, the
value 1U was interpreted as an unsigned char. As a result, explicit
casts are necessary to avoid issues with MISRA 12.2.
