CL: Remove object cache and fix multi-threading
All CL front end objects used to be cached to be able to determine
if an object has been created by the front end to check its validity.
The validity is now checked with the existence of an intrinsic value
(the dispatch table pointer), which is consistent with the patterns
found in Mesa and clvk (though clvk uses a magic value).
This allows the removal of all cached objects.
The cached objects were stored with std::unique_ptr. These are now
gone and all remaining pointers are now custom intrinsic reference
count pointers.
Also remove global lock which causes deadlocks, e.g. when CL API
is called from a separate thread to unlock a blocking call with
a user event. Most of the front end is constant and already
thread-safe. The ref count is also thread-safe now (atomic).
A few remaining locks will follow.
Without the global lock it was now possible to make the API
reentrant, and to remove the workaround with the Khronos ICD
loader to skip ANGLE's OpenCL library.

CL: Add front end object references to back end objects
Add front end object references to back end objects, which requires
a significant amount of refactoring, because the back end objects
have to be constructed during the construction of the front end
objects, so that the references can be passed to the back end objects,
which then can be passed to the front end member initialization.
That would have been easier with inheritance than with PImpl.

CL: device partitioning for front end and passthrough
Partitioning is the creation of sub-devices. Also add reference
counting for CL objects, which is needed now for sub-devices.
Also fix CL print format strings, since cl_ulong is actually
always 64 bit and not unsigned long.
