gn: Optionally disable optimizations and HLSL
To reduce the binary size of ANGLE, a gn override is added
(glslang_angle) which:
- Controls whether ENABLE_OPT=1 is set
- Customizes the build for the Vulkan backend of ANGLE. As a first
step, this removes HLSL functionality which together with no
optimization shave ~2.5MB off of ANGLE's binary size.
Upcoming changes will add a macro for GLSLANG_ANGLE similar to
GLSLANG_WEB that will strip features from glslang to support only what
ANGLE needs.
