Fixed CL_DEVICE_TYPE_ALL to be a long type to avoid sign extension

[coldav]

Description

This fixes CL_DEVICE_TYPE_ALL to be passed correctly to OpenCL backend by changing the immediate for CL_DEVICE_TYPE_ALL to be have the suffix 'L' which avoids the sign extension and removes the previous workaround for Codeplay as a backend.

Problem description

CL_DEVICE_TYPE_ALL was not being correctly provided to OpenCL backends. The CL_DEVICE_TYPE_ALL enumeration was coming out as 0xffffffffffffffff rather than 0xffffffff when used with clGetDeviceIDs which was causing some OpenCL backends to fail as it was passing a technically incorrect value. This can be seen by building Codeplay "host" target - https://github.com/codeplaysoftware/oneapi-construction-kit/blob/main/doc/developer-guide.md#compiling-oneapi-construction-kit

Thank you @coldav . This makes sense. I wish Java has unsigned primitive types.

Pending action is the CLA. It needs to be singed with the same email as the author commit.
