bpf: Rename ARG_CONST_SIZE{,_OR_ZERO} to ARG_MEM_SIZE{,_OR_ZERO}
ARG_CONST_SIZE does not require a constant: check_mem_size_reg() accepts
any bounded scalar and verifies the memory access against its maximum
(reg_umax). Rename ARG_CONST_SIZE and ARG_CONST_SIZE_OR_ZERO to
ARG_MEM_SIZE and ARG_MEM_SIZE_OR_ZERO to reflect that. ARG_CONST_ALLOC_
SIZE_OR_ZERO, which does require a constant, is left unchanged.
Pure rename, no functional change.
