Currently HIP toolchain uses Driver::GetTemporaryDirectory to
create a temporary directory for some temporary files during
compilation. The temporary directories are not automatically
deleted after compilation. This slows down compilation
on Windows.

Switch to use GetTemporaryPath which only creates temporay
files which will be deleted automatically.

This change is OK for MacOS as lipo does not requires specific
file names (https://ss64.com/osx/lipo.html)
