This patch adds support for meta data in the GPU compositor much like the mechanism that already exist in the CPU compositor. Only Cryptomatte meta data is handled at the moment because that is the only meta data that the compositor supports. The is_data member of the result was moved to the meta data structure for consistency with the CPU compositor. Fixes #124222. Pull Request: https://projects.blender.org/blender/blender/pulls/124460
