Move double precision tests from Core to Double class

Move 11 double-precision related tests from DxilConf_SM69_Vectorized_Core
to DxilConf_SM69_Vectorized_Double as suggested by mmerecki in PR #8134.

Tests moved:
- CastToFloat64_* (9 variants for different source types)
- AsDouble_uint32_t
- AsUint_SplitDouble_double

These tests now use HLK_TEST_DOUBLE macro to associate them with the
Device.Graphics.D3D12.DXILCore.ShaderModel69.DoublePrecision specification.
