Fp16 math bruteforce staging (#1863)

* Enable fp16 in math bruteforce

* Added modernization of remaining half tests for consistency (issue #142, bruteforce)

* Added kernel types related corrections

* Added more fixes and general cleanup

* Corrected ULP values for half tests (issue #142, bruteforce)

* Corrected presubmit check for clang format

* Added support for ternary, unary_two_result and unary_two_result_i tests for cl_half (issue #142, bruteforce)

* Added missing condition due to vendor's review

* code format correction

* Added check for lack of support for denormals in binary_half scenario

* Corrected procedure to compute nextafter cl_half for flush-to-zero mode

* Added correction for external check of reference value for nextafter test

* Added correction due to code review request

* Changed quantity of tests performed for half in unary and macro_unary procedures from basic

* Added corrections related to code review:

-added binary_operator_half.cpp and binary_two_results_i_half.cpp
-address sanitizer errors fixed
-extending list of special half values
-removed unnecessary relaxed math references in half tests
-corrected conditions to verify ulp narrowing of computation results
-several refactoring and cosmetics corrections

* Print format correction due to failed CI check

* Corrected bug found in code review (fp16 bruteforce)

* Corrections related to code review (cl_khr_fp16 support according to #142)

-gHostFill missing support added
-special half values array extended
-cosmetics and unifying

* clang format applied

* consistency correction

* more consistency corrections for cl_fp16_khr supported tests

* Corrections related to code review (bureforce #142)

* Correction for i_unary_half test capacity

* Corrections related to capacity of cl_khr_fp16 tests in bruteforce (#142)
