lx_emul: consolidate SMP + NO_HZ_IDLE
* Move common SMP and NO_HZ_IDLE variables and functions into generic lx_emul shadow implementations, and integrate them into the common lx_emul import rules * Enable SMP and NO_HZ_IDLE within virt_linux kernel configuration * Adapt pc drivers and wireguard accordingly * Use original Linux softirq implementation in wireguard * Remove erroneous softirq shadow implementation Ref genodelabs/genode#4540 Ref genodelabs/genode#4562
