Custom aes ciphers will be placed into multiple new files
(instead of the monolithic setup used in the e_aes.c legacy code)
so it makes sense to have a header for the platform specific
code that needs to be shared between files.
modes_lcl.h has also moved to modes_int.h to allow sharing with the
provider source.
Code that will be common to AEAD ciphers has also been added. These
will be used by seperate PR's for GCM, CCM & OCB.

SIV mode is accessible via EVP. There should be no reason to make the low
level SIV functions from the modes directory part of the public API. Since
these functions do not exist in 1.1.1 we are still able to make this change.
This also reduces the list of newly added undocumented symbols from
issue #9095.
