Remove FenceInfo. Instead use GpuProcessFencesHolderId and GpuProcessD3D11FencesHolderMap. GpuProcessD3D11FencesHolderMap is changed to instantiate also in Parent process when GPU process does not exist. Then it seems better to change its name. The name change is going to be handled in Bug 1958752. Differential Revision: https://phabricator.services.mozilla.com/D244539
