16k: core: Change default TARGET_MAX_PAGE_SIZE_SUPPORTED to 16384

Browse Source 
Changing TARGET_MAX_PAGE_SIZE_SUPPORTED default from 65536 to 16384 as
this would reduce the ELF alignment for files and thereby also
decreasing the padding required. Although increased padding does not
result in increased disk space (due to holes), it increases file
metadata. Reducing ELF alignment also helps reduce page table memory as
it reduces number of memory pages utilized / virtual memory address
mappings.

Test: lunch <target> && get_build_var TARGET_MAX_PAGE_SIZE_SUPPORTED
