dev-util/opencl-headers: new package

The first release of unified Khronos OpenCL headers, which unlike
old headers (which is what app-eselect/eselect-opencl installs)
work with all released OpenCL versions rather than having different
versions supported by files from different directories.

Note that in order to avoid file collisions with eselect-opencl this
package presently installs header files into
/usr/$(get_libdir)/OpenCL/vendors/opencl-icd-loader/include ,
which is why it needs multilib support and why it will likely not work
right when installed standalone (in contrast to being pulled in by
dev-libs/opencl-icd-loader).

+		The OpenCL API headers in this package are unified headers and are designed to work
+		with all released OpenCL versions. This differs from previous OpenCL API headers,
+		where version-specific API headers either existed in separate branches, or
+		in separate folders in a branch.
+
+		By default, the OpenCL API headers in this repository are for the latest OpenCL
+		version supported. To use these API headers to target a different OpenCL version,
+		an application may #define the preprocessor value CL_TARGET_OPENCL_VERSION before
+		including the OpenCL API headers. The CL_TARGET_OPENCL_VERSION is a three digit
+		decimal value representing the OpenCL API version.
