Fix translation of storeOp "clear" on Metal 

Previously, resolve was not performed if storeOp was "clear".
Resolve should occur iff a resolveTarget is provided, regardless of
storeOp - storeOp only controls the regular render target.

Test: webgpu:api,operation,render_pass,resolve:render_pass_resolve:*
Test: MultisampledRenderingTest.ResolveInto2DTexture
