This changes compilation of subgroup test kernels so that a separate
compilation is no longer performed for each divergence mask value.
The divergence mask is now passed as a kernel argument.
This also fixes all subgroup_functions_non_uniform_arithmetic testing
and the sub_group_elect and sub_group_any/all_equal subtests of the
subgroup_functions_non_uniform_vote test to use the correct order of
vector components for GPUs with a subgroup size greater than 64.
The conversion of divergence mask bitsets to uint4 vectors has been
corrected to match code comments in WorkGroupParams::load_masks()
in test_conformance/subgroups/subhelpers.h.

Note that this also corrects the start messages logged for the
sub_group_ballot_bit_count/find_msb/find_lsb tests.

* 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

* Report unsupported extended subgroup tests as skipped rather than passed
Also don't check the presence of extensions for each sub-test.

* subgroups: Fix setting cl_halfs and progress check.
cl_float testing uses set_value such that a generated cl_ulong of 1 is
stored as 1.0F in a logical sense. However, cl_half values aren't
intrinsic to C++ and generated cl_ulongs less than 1024 in particular
are interpreted bitwise as subnormals. The test fails on compute devices
lacking subnormal support. Perform the logical conversion to cl_half.
Fix independent forward progress check.
* subgroups_half: Address review comments
* subgroups_half: Formatting fixes required by check-format
* subgroups_half: Modified to query and use rounding mode supported by device
