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.
