Niklas Haas 5bcac8580d spirv: remove --spirv-compiler=nvidia
This option has been deprecated upstream for a long time, probably
doesn't even work anymore, and won't work moving forwards as we replace
the vulkan code by libplacebo wrappers.

I haven't removed the option completely yet since in theory we could
still add support for e.g. a native glslang wrapper in the future. But
most likely the future of this code is deletion.

As an aside, fix an issue where the man page didn't mention d3d11.
