include: mask computed auth/proto bitmasks to 32 bits

Browse source 
GCC 15.2 warns when assigning computed "all" bitmask macros to 32-bit
flag types because negated masks expand to the full width of unsigned
long/long on 64-bit platforms.

Mask these macros to a 32-bit domain so they do not set high bits and
avoid -Woverflow/-Wconversion warnings in callers.
