Support 16KB page size devices

[jstewart5000]

Description:

In Android 15 support for 16KB page sizes has been announced.

However,libfbjni.so ELF segments are not aligned (UNALIGNED (212)) using 16 KB ELF alignment. This results in runtime crash when loading libfbjni.so on emulator that is configured to use 16KB page size:

/tmp/my_apk_out/lib/arm64-v8a/libfbjni.so: UNALIGNED (212)

How To Reproduce:

• This can also be verified by preparing and running alignment.sh script as described in the documentation.
• The solution is to compile libfbjni.so with 16KB ELF alignment as described here.

Environment

• Android Emulator 35.1.4
• Google APIs Experimental 16k Page Size arm64 System Image - API Level VanillaIceCream - Revision 1
