enhance: Enable score based balance channel policy (#38143)
issue: #38142
current balance channel policy only consider current collection's
distribution, so if all collections has 1 channel, and all channels has
been loaded on same querynode, after querynode num increase, balance
channel won't be triggered.

This PR enable score based balance channel policy, to achieve:
1. distribute all channels evenly across multiple querynodes
2. distribute each collection's channel evenly across multiple
querynodes.
