std: add generic target for spirv

This adds a general target for SPIR-V compilation. Previously there was not
any target machine defined for SPIR-V.

TODO is to reword the features for this target. We don't really need the full
list of capabilities in the features, we should only put a few features here
which we can actually use during code generation.
