qca-wifi: Add versions for RDK Plume Stats

Currently there is only a provision to enable
and disable RDK stats with enable_rdk_stats
INI configuration

Since there are new set of statistic metrics added
as part of RDK stats, add version information into
CFG INI configuration such as

0. For disabling stats (By default)
1. For enabling peer rate stats only
2. For enabling peer link metrics only
3. For enabling both statistics

This is done to avoid unncessary CPU consumption
and memory consumption for each peer, depending on
the requirement the version can be enabled
