alloc_tag: add size-based filtering to ioctl

Extend the allocinfo filtering mechanism to allow users to filter tags
based on the total number of bytes allocated [min_size, max_size].  The
size range is inclusive.

Filtering by size involves retrieving allocinfo per-CPU counters, which is
an expensive operation.  Hence, the performance of size-based filtering
will be worse than other filters.
