Vulkan: Set set/binding in SPIR-V
This change introduces a SPIR-V transformer that modifies shader
interface variable decorations directly in SPIR-V instead of
manipulating the input GLSL. Currently, descriptor set and binding
indices are set by the transformer.
The shader translator outputs arbitrary set and binding indices. Once
compiled by glslang, the SPIR-V transformer modifies these decorations.
The ultimate goal is to be able to modify the SPIR-V again when program
pipeline objects decide a different set/binding is necessary.

Implement Draw base vertex and base instance functions
This patch implements functionality of glDrawArraysInstancedBaseInstanceANGLE,
glDrawElementsInstancedBaseVertexBaseInstanceANGLE,
glMultiDrawArraysInstancedBaseInstanceANGLE,
and glMultiDrawElementsInstancedBaseVertexBaseInstanceANGLE
Workaround for OpenGL driver on Mac:
gl_VertexID on Mac with AMD GPU doesn't include baseVertex value.
So replace gl_VertexID with (gl_VertexID + angle_BaseVertex) if any.
Workaround for Vulkan GLSL:
gl_InstanceIndex on Vulkan includes baseInstance. So replace
gl_InstanceIndex with (gl_InstanceIndex - angle_BaseInstance) when
angle_BaseInstance is declared.

Add flags to shader translator to emulate gl_BaseVertex and gl_BaseInstance
Adds support for translating gl_BaseVertex and gl_BaseInstance for implementation of
GL_ANGLE_base_vertex_base_instance.
They will only be available in WebGL 2. Since there's no gl_VertexID and
gl_InstanceID in WebGL 1. It won't be very useful to add them to WebGL
1.
Mostly follow pattern of gl_DrawID of GL_multi_draw
