This commit extends the `ResourceLimitsAttr` to support specifying a minimal and maximal subgroup size, and extends `EntryPointABIAttr` to support specifying the requested subgroup size. This is possible now in Vulkan with the VK_EXT_subgroup_size_control extension. For OpenCL it's possible to use the `SubgroupSize` execution mode directly.
