LoongArch: enable ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP
The feature of minimizing overhead of struct page associated with each
HugeTLB page is implemented on x86_64. However, the infrastructure of
this feature is already there, so just select ARCH_WANT_HUGETLB_PAGE_
OPTIMIZE_VMEMMAP is enough to enable this feature for LoongArch.
