vkd3d-shader: Introduce SPIRV_ENVIRONMENT_VULKAN_1_1.

Browse Source 
The SPIR-V backend may emit SPIR-V 1.3 if Vulkan 1.1 is available.
Some extensions which provide wave op instructions are available in
SPIR-V 1.0, but these are not sufficient to implement all Shader Model 6
wave op intrinsics. SPIR-V 1.3 has all of the required instructions, but
does not support reading from a quad at a non-constant (but uniform) lane
index, so it may later prove necessary to introduce a Vulkan 1.2
environment.
