16k: Align shared libraries and executables to 4k by default
The default ELF segment alignment will be 4096. This alignment
can be overriden by setting the desired alignment in
PRODUCT_MAX_PAGE_SIZE_SUPPORTED flag. The alignment has to be
a multiple of the configured kernel page size.
Test: Built changes for Pixel 4a, 6 and checked alignment.
