1. Add option to enforce fragment execution with side effects in MSL …

   Metal will incorrectly discard fragments with side effects under
   certain circumstances prematurely. The conditions are the following:
    - Fragment will always be discarded after side effect operation
    - Pre fragment depth fails
    - Modifies depth value for a constant value in the fragment shader.
      This constant value will also fail the depth test.
   
   However, Metal will also discard the fragment even if it has
   operations with side effects inside the fragment shader before the
   discard operation.
   
   Vulkan states the graphics pipeline to execute in the following
   order:
    - Pre fragment depth test (cannot discard here due to modifying
      depth value in fragment shader)
    - Fragment shader (where the depth is modified and fragment
      discarded)
    - Post fragment depth test
   
   Therefore, we need to enforce fragment shader execution and not
   let Metal discard the fragment before that for such cases. This
   change adds an option to provide such utility.
