Subject: [PATCH] Boosting kswapd uclamp min value when the panel is on

Boosting kswapd's uclamp minimum value in the scheduler
allows kswapd more opportunities to remain in middle cores.
This change enhances kswapd's memory reclamation efficiency.

Bug: 351708752
Test: check kbnob value when the panel is on/off
Flag: EXEMPT device policy tuning
