272ce90e - [Clang] Make OpenMP offloading consistently use the bound architecture (#125135)

[Clang] Make OpenMP offloading consistently use the bound architecture (#125135) Summary: OpenMP was weirdly split between using the bound architecture from `--offload-arch=` and the old `-march=` option which only worked for single jobs. This patch removes that special handling. The main benefit here is that we can now use `getToolchainArgs` without it throwing an error. I'm assuming SYCL doesn't care about this because they don't use an architecture.
