CL: Add CL command execution status to the enum list Adding the CL command execution status enums to the auto enum generation list - packed_cl_enums.json. The execution status are defined as cl_int in the CL api, and as such they are not packed at the entry points - entry_points_cl_autogen.{h,cpp}, and are left to be used at the implementation layer. The following files are autogeneration through `run_code_generation.py` script. - scripts/code_generation_hashes/packed_enum.json - src/common/PackedCLEnums_autogen.cpp - src/common/PackedCLEnums_autogen.h Bug: angleproject:37997556 Change-Id: Ia00fc12ef02e3882d47a1ad18cd6c11ce6bf63dc Signed-off-by: Gowtham Tammana <g.tammana@samsung.com> Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/6004062 Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org>
