[Offload][clang-linker-wrapper][SPIRV] Tell spirv-link to not optimize out exported symbols (#182930)
`spirv-link` seems to internalize all symbols, which ends up causing the
OpenMP Device Environment global generated by the OMP FE to get
optimized out which causes `liboffload` to run in the wrong
parallelization mode which breaks at least one liboffload lit test.

Pass `--create-library` to tell it not to do that.

```
  --create-library
               Link the binaries into a library, keeping all exported symbols.
```

This fixes the test.

The LLVM/Offload Subproject

The Offload subproject aims at providing tooling, runtimes, and APIs that allow users to execute code on accelerators or other "co-processors" that may or may not match the architecture of their "host". In the long run, all kinds of targets are in scope of this effort, including but not limited to: CPUs, GPUs, FPGAs, AI/ML accelerators, distributed resources, etc.

For OpenMP offload users, the project is ready and fully usable. The final API design is still under development. More content will show up here and on our webpage soon. In the meantime, people are encouraged to participate in our meetings (see below) and check our development board as well as the discussions on Discourse.

Meetings

Every second Wednesday, 7:00 - 8:00am PT, starting Jan 24, 2024. Alternates with the OpenMP in LLVM meeting. invite.ics Meeting Minutes and Agenda
