mlxsw: Add support for TC flower offload statistics

Arkadi says:
This patchset adds support for retrieving TC flower statistics for
offloaded rules, which includes packets count, bytes count and last used
time stamp. Currently The statistics are gathered on a per-rule basis.

This patchset also includes generic allocator for counters.
