16k: core: Add defaults for TARGET_MAX_PAGE_SIZE_SUPPORTED
This refactors existing validation logic to do the following:
- Default ELF alignment to 4096 for non-(arm64/x86_64) targets.
- Default ELF alignment to 4096 if VSR_VENDOR_API_LEVEL < 34.
Test: lunch <target> && get_build_var TARGET_MAX_PAGE_SIZE_SUPPORTED
