pagemap: add page-types tool

Add page-types, a handy tool for querying page flags.

It will expand some of the overloaded flags:
	PG_slob_free   = PG_private
	PG_slub_frozen = PG_active
	PG_slub_debug  = PG_error
	PG_readahead   = PG_reclaim

and mask out obscure flags except in -raw mode:
	PG_reserved
	PG_mlocked
	PG_mappedtodisk
	PG_private
	PG_private_2
	PG_owner_priv_1
	PG_arch_1
	PG_uncached
	PG_compound* for non hugeTLB pages
