Avoid full compaction when apps move within Cached bucket

Browse Source 
This patch reduces the amount of times we trigger full compactions
that currently happen at any OOM adjust change when the app is
within the Cached state bucket as it was identified that there
were many instances of this situation.

Bug: 232311101
Test: Checked that the number of full compactions went down in
dumpsys activity
