Is your feature request related to a problem? Please describe.

Linker fully abstracts the linking details away from the user, but in certain cases the user might need to query the backend. For example, a user linking static code might prefer to pass ltoir rather than ptx if they know nvjitlink is available. Linker.backend exposes this property but requires instantiating a Linker instance to query. We should make it possible to get the info without doing so.

Describe the solution you'd like

I'd like Linker.backend to return driver or nvjitlink without instantiating the class

Describe alternatives you've considered

Instantiating a LinkerOptions in a function that catches the warning
