bpf: arena: Reintroduce memcg accounting

When arena allocations were converted from bpf_map_alloc_pages() to
kmalloc_nolock() to support non-sleepable contexts, memcg accounting was
inadvertently lost. This commit restores proper memory accounting for
all arena-related allocations.

All arena related allocations are accounted into memcg of the process
that created bpf_arena.
