package/opencl-headers: new package

Browse Source 
Add the "opencl-headers" package to install the OpenCL C API headers,
which are required at build time by consumers such as
opencl-icd-loader.

While Mesa provides these headers internally, they are not installed
by default since clover and opencl-gallium are deprecated and will
be removed starting from mesa 25.2

And since we should install them manually from mesa, it is better
use external headers. This ensures these headers are always
available and up-to-date independently from those provided by Mesa,
folowing the same logic used for "opencl-clhpp".
