stupidgcm: introduce stupidAEADCommon and use for both chacha & gcm
Nice deduplication and brings the GCM decrypt speed up to par. internal/speed$ benchstat old new name old time/op new time/op delta StupidGCM-4 4.71µs ± 0% 4.66µs ± 0% -0.99% (p=0.008 n=5+5) StupidGCMDecrypt-4 5.77µs ± 1% 4.51µs ± 0% -21.80% (p=0.008 n=5+5) name old speed new speed delta StupidGCM-4 870MB/s ± 0% 879MB/s ± 0% +1.01% (p=0.008 n=5+5) StupidGCMDecrypt-4 710MB/s ± 1% 908MB/s ± 0% +27.87% (p=0.008 n=5+5)
