16k: core: Check that TARGET_MAX_PAGE_SIZE_SUPPORTED is greater than 4096 only for ARM archs.

Browse Source 
For arm archs, PRODUCT_MAX_PAGE_SIZE_SUPPORTED  values can be 4096, 16384, 65536.
For other archs, PRODUCT_MAX_PAGE_SIZE_SUPPORTED can only be 4096.

Note: The linker flag max-page-size is configured by PRODUCT_MAX_PAGE_SIZE_SUPPORTED flag.

Bug: 289419664

Test: source build/envsetup.sh
      lunch aosp_cf_x86_64_phone
      build/make/core/config.mk:448: error: TARGET_MAX_PAGE_SIZE_SUPPORTED=65536 is greater than 4096. Only supported in ARM arch.

      source build/envsetup.sh
      lunch aosp_raven_64-userdebug
