Added cl_khr_fp16 extension support for test_commonfns (#1695)

* Added cl_khr_fp16 extension support for commonfns test (issue #142, commonfns)

* Added missing header due to presubmit check

* Corrected radians/degrees ulp calculations + cosmetic fixes

* Corrected presubmit code format

* Corrections related to code review

* Moved string format helper to test_common in separate header

* Added clang format for last commit

* Corrections related to code review

* Modified mix verification procedure for half type to only report max error

* Removed redundant condition for logging mix verification

* Corrected generator limits for half tests
