test_computeinfo: need special check for built-in kernel name_version and string if no built-in kernels are supported

For `CL_DEVICE_BUILT_IN_KERNELS`: An empty string is returned if no built-in kernels are supported by the device.
For `CL_DEVICE_BUILT_IN_KERNELS_WITH_VERSION`: The list of reported kernels must match the list returned via `CL_DEVICE_BUILT_IN_KERNELS`.

so, if a device has no supported built-in kernels, it may return `{CL_MAKE_VERSION(0, 0, 0), ""}`, when querying `CL_DEVICE_BUILT_IN_KERNELS_WITH_VERSION`

CST may add special validation for this scene.

Thanks!

Start with the test_computeinfo implementation and its checks for CL_DEVICE_BUILT_IN_KERNELS and CL_DEVICE_BUILT_IN_KERNELS_WITH_VERSION. Confirm the empty-kernel case and ensure the versioned query accepts {CL_MAKE_VERSION(0, 0, 0), ""} when no built-in kernels are supported, while otherwise matching the reported kernel list.
