Metal: Add workaround for imageAtomic synchronization issue

Browse Source 
A compiler/driver bug makes so that we can't rely on image atomics.

Adding a write that is never executed after the atomics tricks
the compiler to issue the correct synchronisation instruction.

This fixes a bunch of our render tests differences.

We will keep this workaround until this is fixed upstream.
