Finish renaming of SPV_INTEL_tensor_float32_conversion (#3033)

New name is SPV_INTEL_tensor_float32_rounding. It's already recognized
by older release branches of llvm-spirv.
If a frontend faces an issue with this patch, the following update is
needed:
```
- --spirv-ext=...+SPV_INTEL_tensor_float32_conversion...
+ --spirv-ext=...+SPV_INTEL_tensor_float32_rounding...
```
