For architectures that define __HAVE_ARCH_TLB_REMOVE_TABLE, the page tables at the pmd/pud level are generally not of struct ptdesc type, and do not have pt_rcu_head member, thus these architectures cannot support PT_RECLAIM. In preparation for enabling PT_RECLAIM on more architectures, convert __HAVE_ARCH_TLB_REMOVE_TABLE to CONFIG_HAVE_ARCH_TLB_REMOVE_TABLE config, so that we can make conditional judgments in Kconfig.
