jit: implement gcc_jit_context_new_rvalue_from_vector

This patch implements a new API entrypoint:

/* Build a vector rvalue from an array of elements.

   "vec_type" should be a vector type, created using gcc_jit_type_get_vector.

   This API entrypoint was added in LIBGCCJIT_ABI_10; you can test for its
   presence using
     #ifdef LIBGCCJIT_HAVE_gcc_jit_context_new_rvalue_from_vector
*/
