vpp: T8266: Add global `interfaces-rx-mode` setting and remove per-interface commands

Add `set vpp settings interfaces-rx-mode <polling|interrupt|adaptive>`
to configure RX mode for all interfaces. Raise error if any interface
does not support the selected mode.

Also remove per-interface rx-mode commands:
  - `set vpp settings interface <name> rx-mode`
  - `set vpp kernel-interfaces <name> rx-mode`
