Extended subgroups - use 128bit masks (#1215)

Browse Source 
* Extended subgroups - use 128bit masks

* Refactoring to avoid kernels code duplication

* unification kernel names as test_ prefix +subgroups function name
* use string literals that improve readability
* use kernel templates that limit code duplication
* WorkGroupParams allows define default kernel - kernel template for multiple functions
* WorkGroupParams allows define  kernel for specific one subgroup function
