lmkd: change defaults to disable event upgrade/downgrade logic 

vmpressure upgrade/downgrade logic based on swap utilization works well
for low memory devices because of a small swap size, however for high
performance devices this measure is not a good indication of the memory
pressure because of large swap resources. This change sets the default
levels to disable upgrade/downgrade logic by default and each device
can set these properties appropriately.

Bug: 63631020
Test: alloc-stress
