  [HLSL] Explicitly set the SPIR-V version with spv-target-env (#121961)

In DXC, setting the vulkan version automatically sets the target spir-v
version to the maximum spir-v version that the vulkan version must
support. So for Vulkan 1.2, we set the spir-v version to spirv 1.5
because every implementation of Vulkan 1.2 must support spirv 1.5, but
not spir-v 1.6.
