CL: Create frontend event and pass to enqueue APIs
Since frontend cl_event object does not depend on enqueue
API routines, we can construct it early and then pass to
mImpl enqueue API calls (for any backend that needs it).
Also update backend routines to init their backend
event implementations using frontend event object.

CL: Update event creation routines
Move backend construction after frontend construction
completes. This avoids potential undefined behavior
if backend construction tries to access members of
half-constructed frontend object.
Add virtual onEventCreate routine for any actions that
need to be performed after cmd event has been created.
Additionally, this also fixes incorrect timestamp values
when queue profiling is enabled for the VK backend.
This was due to a missed event association to the
cmd queue.

OpenCL: Update CLtypes.h to cl_types.h
This change/enhancement is to keep codebase more consistent since
vulkan backend versions of this header use lowercase-snake_case for
file name.

OpenCL: Replace error-return APIs to use angle::Result
The motivation of converting existing CL APIs using
"cl_int errorCode" to now use "angle::Result" is for better
interop with internal ANGLE plumbing/abstractions.
To facilitate this, we now make use of a TLS errorCode
object that we set internally and read from entrypoint/stubs
layer so that we can propagate back to user.

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.
