Untangle build target cyclic dependencies (approach #2)

... and stub the HLSL target.

Fixes the building of shared libraries.

This breaks the cyclic dependency between the `glslang` and `hlsl` targets (by essentially removing the `hlsl` target).

The `BUILD.gn` and `BUILD.bazel` build rules already pull the `HLSL` source into the `glslang` target.

`Android.mk` is the only remaining build config that has a dedicated `HLSL` target, but this is explicity static and does not suffer the same link-time issues with the cyclic dependency (we may wish to stub this target too).

Related issue: #1484, #2147
Related PR: #2267

The `isMat` variable is no longer used in the HLSL parser. Removed.

Related to PR #2265.

This breaks a cyclic dependency between the SPIRV and glslang build targets.

* Fix xfb_stride limit issue

Unsized array can't apply to transform trace. layout qualifier "offset" require GL_ARB_enhanced_layouts enable or glsl core version > 440.

* Add negative test for xfb limit

* update case result

* Fix compile information issue

Fix compile information issue and test comment issue.

* remove es profile condition, use profileRequires to limit.

* Fix xfb_stride limit issue

Unsized array can't apply to transform trace. layout qualifier "offset" require GL_ARB_enhanced_layouts enable or glsl core version > 440.
Add negative test for xfb limit

* Move es profile check out of version number check

* Adjust error information and related cases

remove the new version check, refine original version check.

* Revert condition for vulkan, and remove redundant test code.

* Add Shared/Std140 SSBO process & top-level array elements related
process

1.Add process options for shared/std140 ssbo, following ubo process
2.Add IO Variables reflection option, would keep all input/output
variables in reflection
3.Add Top-level related process, fix top-level array size issues,
following spec
4.Split ssbo/ubo reflection options, merge blowup expanding all into
function blowupActiveAggregate to allow other functions keep same entry
format.

Add options in StandAlone and test symbols.

1. Add options in StandAlone for std140/shared ubo/ssbo and all io variables reflection.
2. Add test for ssbo. When EShReflectionSharedStd140SSBO turns on, generated symbol and output would be different, to remind the difference. Defaultly disabled and nothing would change, nor blocking normal test.

* Add options in runtest script, refresh test results.

Add options in StandAlone:
--reflect-all-io-variables --reflect-shared-std140-ubo --reflect-shared-std140-ssbo

refresh test results.
Now the index, size of unsized array are expected.

If a uniform has an initializer it will now be given as the optional
initializer operand to the OpVariable instruction.

Fixes #2198.

* HLSL: Fix handling of uniforms in entry point parameters

* HLSL: fix handling of "uniform in"

* Tests: Update baseResults of hlsl.function.frag.out for #2254

* HLSL: fix uniforms in function parameters for opaque types

variables.

This CL updates the build scripts to only install to glslang/SPIRV
instead of also installing to the SPIRV/ folder. The deprecation notice
is also removed.

Note, this may cause downstream build issues if include directories have
not been updated

Fixes #1964 #2216

* EXT_ray_tracing requires spv1.4

* Fix typo.

* Add extension data table.

* Updated feedback #2.

Fixes #1553

* Update known good SPIRV-Tools

* Update test expectations

Fixes field reorder warning.

* Add support for primitive culling layout qualifier.

* Add error checks for primitive flags and negative test.

when using multiple compilation units, input/output layouts don't need
to be declared in every unit.

* Add an option to make Exceptions enabled

* /EHsc enable exceptions since vs2003

Add check for DOUBLE in low versions, fix issue #2206

Specifically, add flattening of arrayed io for geometry and
tesselation shaders. Previously some interface structs just had
builtins split out which caused some interfaces to not be exactly
the same as that of flattened adjacent stages, affecting validation
and correctness.

This obviates builtin splitting. That will be removed in a followup
commit. It was left in for this commit to better exhibit the functional
changes that were made.

Fixes #1660.
