* [spirv] specify correct SPV env for disassembling
When DXC finishes generating SPIR-V, the binary is disassembled and
printed to stdout.
The target env was hardcoded to Vulkan1.1, meaning disassembly would
fail if we tried disassembling Vulkan1.2+ SPIR-V.

* [spirv] Fix Layer & ViewportIndex ext in 1.2+
Back in Vulkan1.1, ShaderViewportIndexLayer was required to use
SV_RenderTargetArrayIndex. This was promoted in VK1.2:
https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VK_EXT_shader_viewport_index_layer.html
Sadly, DXC didn't checked the target SPV environment, and always
requested the extension. This commit addresses this.
