ANDROID: vendor_hooks: Add hooks to madvise_cold_or_pageout_pte_range()

Browse Source 
Provide a vendor hook android_vh_page_isolated_for_reclaim to
process whether the page should be reclaimed to a specified
swap(i.e., the expanded memory).
This strategy will take into account the state of the current
process/application, resource usage, and other information.
