  [clang][SPIR-V] Use the SPIR-V backend by default (#129545)

The SPIR-V backend is now a supported backend, and we believe it is
ready to be used by default in Clang over the SPIR-V translator.

Some IR generated by Clang today, such as those requiring SPIR-V target
address spaces, cannot be compiled by the translator for reasons in this
[RFC](https://discourse.llvm.org/t/rfc-the-spir-v-backend-should-change-its-address-space-mappings/82640),
so we expect even more programs to work as well.

Enable it by default, but keep some of the code as it is still called by
the HIP toolchain directly.
