[libclc][NFC] Fix build warning typedef-redefinition (#177888)
Fix downstream build warning:
redefinition of typedef 'ushort8' is a C11 feature [-Wtypedef-redefinition]
clctypes.h re-defines typedef from opencl-c-base.h. Both files are
included in libclc/opencl folder.
This PR deletes clctypes.h and includes opencl-c-base.h for both CLC and
OpenCL libraries.
Previously opencl-c-base.h was only included in OpenCL library.
