Add external semaphore tests. (#1645)

* Add external semaphore tests.

Added basic test to check the functionality of cl_ext_external_semaphore_test extension.
Tests rely on Vulkan API as the producer of the external semaphore functionality. The
Vulkan wrapper has been copied from the Vulkan CTS tests and minor changes have been
introduced. A separate copy of the Vulkan wrapper is for breaking any dependencies
between different CTS modules and thus make the build system simpler.

* Fix clang-format

* Move vulkan wrapper to a separate library.

Vulkan wrapper is extracted as a separate module and can be used in different
CTS tests as a shared library.

* Add cl_ext_external_samaphore tests based on cl_khr_semaphore tests.

Added cl_khr_semaphore adjusted to creating semaphores in Vulkan context
and importing them through export semaphore functionality in OpenCL
(cl_ext_external_samaphore).

compilation arguments.
