16k: Define PRODUCT_MAX_PAGE_SIZE_SUPPORTED flag
The PRODUCT_MAX_PAGE_SIZE_SUPPORTED will be used to define the
ELF segment alignment of the binaries (executables and shared
libraries). The alignment is set based on these conditions:
- If PRODUCT_MAX_PAGE_SIZE_SUPPORTED is defined, that value will be
used to align the binaries. If not defined, see condition below:
- If it is a low memory device, 4096 will be the alignment. If it is
not low memory device, see conditon below:
- If VSR vendor API level < 34, 4096 will be the alignment, otherwise
it will be 65536.
Test: Built for in Pixel 4a, 6 and verified the alignment with readelf.
