Reimplement Neon FP8 vector types using attribute `neon_vector_type` instead of having them as builtin types. This allows to implement FP8 Neon intrinsics without the need to add special cases for these types when using `__builtin_shufflevector` or bitcast (using C-style cast operator) between vectors, both extensively used in the generated code in `arm_neon.h`.
