scx_qmap: Implement highpri boosting
Implement a silly boosting mechanism for nice -20 tasks. The only purpose is
demonstrating and testing scx_bpf_dispatch_from_dsq(). The boosting only
works within SHARED_DSQ and makes only minor differences with increased
dispatch batch (-b).
This exercises moving tasks to a user DSQ and all local DSQs from
ops.dispatch() and BPF timerfn.
v2: - Updated to use scx_bpf_dispatch_from_dsq_set_{slice|vtime}().
- Drop the workaround for the iterated tasks not being trusted by the
verifier. The issue is fixed from BPF side.
