  Message : Add a gl-d3d-only target for the translator Chrome's validating command decoder links statically with the ANGLE translator. This change adds a target that builds the translator with only gl and d3d support for this purpose. This will prevent chrome from linking against glslang because of the Vulkan backend. As a bonus, it will reduce the binary size of Chrome by stipping the Vulkan and Metal translation and transformation codes.
