Update CHANGES for 11.3.0

Update spirv-tools and spirv-headers known good

Exposed #856 as --hlsl-sampled-textures in the StandAlone

Add a --depfile option in Standalone mode

The output is similar to gcc -MMD and can be used by build systems
like meson to automatically recompile shaders if an included header
was changed.

TextureOffset not support sampler2DArrayShadow sampler until 430.

Typo in ShaderLang.h

Fix builtins for GL_EXT_shader_explicit_arithmetic_types for es

Issue error when declaration rule fails

Add IntLog2 and use it

Replace uses of floating point log2 when we want an integer result from
an integer operand.  This avoids concerns about accuracy of floating
point library functions.

Get rid of extra semicolon causing gcc 10.3 troubles.

Removed condition for glslang-default-resource-limits instalation.

Fix table key and whitespace

These got lost in the wash with my last revert but are still relevant.

Fix #2514.

Add setter for TInterimSelection.condition

This way the limits are available to clients that links statically.

Revert "Update minimum SPIR-V requirement for GL_EXT_buffer_reference"

Do not propagate packing qualifiers to scalars or vectors

Packing qualifiers have no practical effect on scalars or vectors
so this is unnecessary and its confusing tools downstream that
consume the AST.

Update minimum SPIR-V requirement for GL_EXT_buffer_reference

Fix SPIR-V for HLSL EvaluateAttribute* of interpolants in structs

Generate load of interpolant for first operand to GLSLstd450
InterpolateAt* SPIR-V ops. This allows the interpolants to
propagate from the input struct in the wrapper around main
into the shader during HLSL legalization. A new pass has been
added to legalization which will remove the load and replace
with the pointer of the load to create valid external
interpolate op.

Fixes #2584

For bug #2580: sparseTextureGatherOffsetsARB should only take constant offsets

Require SPIR-V 1.3 when using GL_EXT_buffer_reference.
Migrate tests to SPIR-V 1.3 fixture as necessary.
Fix extension table key.
Fix whitespace.
