[clang][clang-linker-wrapper] Use the correct triple for clang-offload-bundler and AMD SPIR-V. (#168521)
`clang-linker-wrapper` was incorrectly calling `clang-offload-bundler`
for AMD SPIR-V. This resulted in a binary that couldn't be executed if
built using the new driver.
The runtime couldn't recognise the triple triggering this error at
execution time:
```
No compatible code objects found for: gfx90a:sramecc+:xnack-,
```
With this PR, this is solved:
```
Creating ISA for: gfx90a:sramecc+:xnack- from spirv
```
