perf(timer): unify idle to HLT and bump LAPIC tick to 1ms

[Enigamict]

Description

First, On QEMU, CPU threads sometimes spiked to 900–1400% host CPU.
A combination of short-period timers(100 µs)and busy-wait, creating an interrupt reprogramming loop so dense that hlt was rarely reached.

Next, Added the changes below

1. LAPIC timer period from 100 µs → 1 ms to prevent interrupt overruns that keep cores from idling.

With this change, CPU runaway no longer occurs, and the system runs stably on QEMU.

todo: Investigate a strategy to branch timer configuration between QEMU and physical machines, reflecting their markedly different timer behavior.

[Enigamict]

To handle differences between real hardware and virtualized environments, I implemented detection for KVM/QEMU and adjusted the local APIC timer period accordingly.
The CPU sleep subsystem sleep_cpu_no_std::init() and sleep_cpu_no_std::reset_wakeup_timer() now uses wakeup_interval() to perform keep-alive scheduling: 1 ms under KVM/QEMU and 100 µs on bare-metal hardware.
Note that this detection relies on x86_64 CPUID information, so this adaptive timing mechanism is currently limited to the x86_64 architecture.
