This is just a renaming patch, motivated by a need for clarity before addding more YUV formats. Comments and log messages are updated as well, and one function in MacIOSurface is renamed. There is one small change in TextureHost.cpp to satisfy clang-tidy. Differential Revision: https://phabricator.services.mozilla.com/D217883
