The ARCH_MAY_HAVE patch missed arm64, mips and s390. But it may
also lead to arch options being enabled but ineffective because
of modular/built-in conflicts.
As the primary user of all these options wireguard is selecting
the arch options anyway, make the same selections at the lib/crypto
option level and hide the arch options from the user.
Instead of selecting them centrally from lib/crypto, simply set
the default of each arch option as suggested by Eric Biggers.
Change the Crypto API generic algorithms to select the top-level
lib/crypto options instead of the generic one as otherwise there
is no way to enable the arch options (Eric Biggers). Introduce a
set of INTERNAL options to work around dependency cycles on the
CONFIG_CRYPTO symbol.
Fixes: 1047e21aecdf ("crypto: lib/Kconfig - Fix lib built-in failure when arch is modular")
