bpf: add percpu stats for bpf_map elements insertions/deletions
Add a generic percpu stats for bpf_map elements insertions/deletions in order
to keep track of both, the current (approximate) number of elements in a map
and per-cpu statistics on update/delete operations.
To expose these stats a particular map implementation should initialize the
counter and adjust it as needed using the 'bpf_map_*_elem_count' helpers
provided by this commit.
