Limit work group size by the max item size in mutable_command_full_dispatch (#2578)

Browse Source 
The maximum value for the workgroup size in a specific dimension can be
lower than the overall maximum workgroup size. This patch queries for
the maximum work item size in the first dimension and limits the
group_size by that value as well.
