host: lib: convert: Add CMake flag for NEON SIMD
Adding CMake flag to enable/disable NEON SIMD instructions. This is an addition to the previous checks (check for NEON headers and checking the size of pointers), so behavior is unchanged unless users specify that they do not want to use NEON instructions.
