lib/crypto: Switch ARM and arm64 to 'ksimd' scoped guard API
Before modifying the prototypes of kernel_neon_begin() and
kernel_neon_end() to accommodate kernel mode FP/SIMD state buffers
allocated on the stack, move arm64 to the new 'ksimd' scoped guard API,
which encapsulates the calls to those functions.
For symmetry, do the same for 32-bit ARM too.
