[PATCH v3 0/3] firmware_loader: make RUST_FW_LOADER_ABSTRACTIONS select FW_LOADER

I have noticed that build fails when doing the following:

- Start with the x86 defconfig,
- Using nconfig, enable `RUST` and `DRM_NOVA`,
- Start building.

The problem is that `RUST_FW_LOADER_ABSTRACTIONS` remains unselected,
despite it being a dependency of `NOVA_CORE`. This seems to happen
because `DRM_NOVA` selects `NOVA_CORE`.

Fix this by making `RUST_FW_LOADER_ABSTRACTIONS` select `FW_LOADER`, and
by transition make all users of `RUST_FW_LOADER_ABSTRACTIONS` (so far,
nova-core and net/phy) select it as well.

`FW_LOADER` is more often selected than depended on, so this seems to
make sense generally speaking.
