ANDROID: mm: Create hooks for ZONE_MOVABLE allocs
Create a vendor hook inside of gfp_zone() to modify which allocations get to enter ZONE_MOVABLE, by zeroing out __GFP_HIGHMEM inside of the trace hook based on certain conditions. Separately, create a trace hook in the readahead path to affect the behavior of the tracehook in gfp_zone(). In 5.15, we had set_skip_swapcache_flags trace-hook in do_swap_page() but commit ac26e9c7 ("ANDROID: cma: allow to use CMA in swap-in path") added __GFP_CMA explicitly, so the set_skip_swapcache_flags trace hook is no longer needed. Note: To comply with vendor hook guidlines, avoid including types.h in trace/hooks/mm.h and use unsigned int for gfp_t. The original commit included a change to set __GFP_CMA in mm/memory.c, but commit 988dc02c ("BACKPORT: mm: support large folios swap-in for sync io devices") overwrote this, and __GFP_CMA is not currently set in android16-6.12, so in the current commit, we decided to keep the status quo, the missing __GFP_CMA flags will be added in a separate patch.
