Reorder BaseVertexBaseInstance draw calls parameters
To match the parameter order of MultiDraw* calls.
And potentially expose in chromium directly with ANGLE_ prefix.

BaseInstance VertexAttribDivisor fix
Add tests not using gl_InstanceID/gl_BaseInstance but set
vertexAttribDivisor which implicitly reference base instance value.
Add fixes and workarounds based on this change.

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.
