crypto: lib/Kconfig - Fix lib built-in failure when arch is modular
The HAVE_ARCH Kconfig options in lib/crypto try to solve the
modular versus built-in problem, but it still fails when the
the LIB option (e.g., CRYPTO_LIB_CURVE25519) is selected externally.
Fix this by introducing a level of indirection with ARCH_MAY_HAVE
Kconfig options, these then go on to select the ARCH_HAVE options
if the ARCH Kconfig options matches that of the LIB option.
