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.

Vulkan: Call glslang at compile time
With this change, the ANGLE translator immediately compiles the
generated GLSL into SPIR-V with glslang and discards the source. This
is in preparation for generating SPIR-V directly, by making the frontend
and backend already able to digest it.
This change also allows the expensive glslang calls to be parallelized,
improving the following perf test by about 20%:
LinkProgramBenchmark.Run/vulkan_compile_and_link_multi_thread
Previously, the test was run as such in the Vulkan backend:
Main Thread 1 Thread 2
Compile1 --->
Compile2 --------------------->

With this change, it is run as such:

glslang_wrapper_utils no longer interacts with glslang! A rename will
follow.
