Vulkan: SPIR-V Gen: Drop dependency to glslang
The SPIR-V gen path is now made default. Compilation through glslang is
still supported for debugging, and is enabled on the GLSL* end2end tests
for smoke testing. On release builds, glslang is not supported.
To test with glslang, add the following gn arg (only necessary if dcheck
is disabled):
angle_enable_spirv_gen_through_glslang = true
Then enable the generateSPIRVThroughGlslang feature. This can be done
by setting an environment variable:
ANGLE_FEATURE_OVERRIDES_ENABLED=generateSPIRVThroughGlslang ./angle_deqp_gles2_tests
Binary size saving:
- 1.3MB on Linux (SPIR-V gen itself: 240KB)
- 730KB on Android (SPIR-V gen itself: 140KB)
Perf tests:
- LinkProgramBenchmark.Run/vulkan_compile_single_thread
* Through glslang:
truncated mean: 1287033.36
* Direct SPIR-V Gen:
truncated mean: 244495.91 (~80% reduction)
- LinkProgramBenchmark.Run/vulkan_compile_multi_thread
* Through glslang:
truncated mean: 4565894.83
* Direct SPIR-V Gen:
truncated mean: 1158164.10 (~75% reduction)

GN: Update dcheck/assert conditions.
In preparation for a Chromium change that makes dchecks enabled
by default in Release builds, we'll keep ASSERT disabled in
Release by default. We add a new flag 'angle_assert_always_on'
for controlling ANGLE ASSERT behaviour.
Also slightly refactors the direct SPIR-V generation GN.
