  [WGSL] Array length needs to divide size received from the API

Reviewed by Mike Wyrzykowski.

For runtime-sized arrays, since the API doesn't know the type of the array element
(and consequently its size), it just passes the size of the buffer in bytes. The
generate code for `arrayLength(x)` must then include the division by the size of
the array's element type.
