Currently we require the `-fopenmp-targets=` option to specify the triple to use for the offloading toolchains, and the `-Xopenmp-target=` option to specify architectures to a specific toolchain. The changes made in D124721 allowed us to use `--offload-arch=` to specify multiple target architectures. However, this can become combersome with many different architectures. This patch introduces functinality that attempts to deduce the target triple and architectures from the offloading action. Currently we will deduce known GPU architectures when only `-fopenmp` is specified. This required a bit of a hack to cache the deduced architectures, without this we would've just thrown an error when we tried to look up the architecture again when generating the job. Normally we require the user to manually specify the toolchain arguments, but here they would confict unless we overrode them.
