There is little need to support alignments larger than a page size,
and the open-coded OPENSSL_aligned_alloc() implementation implements
that support in quite wasteful manner, so it is better just to limit
the maximum supported alignment explicitly. The value of 65536
has been chosen so it is architecture-agnostic and is no less than page sizes
used in commonly occurring architectures (and also it is a pretty number).

Factor the open-coded aligned allocation implementation in a separate
file and use it instead of just returning NULL in CRYPTO_aligned_alloc
implementation in the FIPS provider.
