More shader refactoring

* Initial Commit

Added Device logic to Sinks
Started on UI for selecting devices

Removed redundant import

* Audio Core: Complete Device Switching

Complete the device switching implementation by allowing the output
device to be loaded, changed and saved through the configurations menu.

Worked with the Sink abstraction and tuned the "Device Selection"
configuration so that the Device List is automatically populated when
the Sink is changed.
This hopefully addresses the concerns and recommendations mentioned in
the comments of the PR.

* Clean original implementation.

* Refactor GetSinkDetails

This doesn't belong in LoadInputVertex because it also happens for
non-VS invocations. Since it's not used by the JIT it seems adequate to
initialize it in the interpreter which is the only thing that cares
about them.

Currently there's only a single dummy implementation, which will be
split in a following commit.
