Remove (all) wrapper macros

[dop-amin]

In #36, the removal of macros that we do not require as wrappers for instructions has been started for load and store instructions.
I think it would be good to also remove the wrappers for arithmetic instructions.

Example: In examples/naive/aarch64/intt_dilithium_1234_5678.s

.macro vmls d,a,b
        mls \d\().4s, \a\().4s, \b\().4s
.endm
