sched_ext: Remove deprecated scx_bpf_cpu_rq()

scx_bpf_cpu_rq() exposes rq pointers without requiring the rq lock and
has emitted a deprecation warning since commit
5c48d88fe004 ("sched_ext: deprecation warn for scx_bpf_cpu_rq()").
The supported replacements cover the intended uses:
scx_bpf_locked_rq() for locked rq access and
scx_bpf_cpu_curr() for remote curr lookup.

Remove the kfunc, its BTF registrations, the deprecation warning
state, and the BPF-side prototype and compat fallback.
