time cross platform

[pointertobios]

整个src中没有对get_highfeq_time_start的其它引用，可以安全地删除
运行所有demo都没发现有问题

Summary by CodeRabbit

• 新功能
  • 计时与延时逻辑升级为统一的高精度时间方案，提升时间计算的一致性与稳定性。
• 改进
  • 帧率统计及多种延时流程改为使用同一计时基准，减少对内部设置状态的依赖。
  • 当延时为 0 时，改为更符合系统调度的让出式等待策略，优化空闲时的 CPU 行为。

Walkthrough

将 get_highfeq_time_ls 改为无参的 std::chrono 实现，并同步移除相关结构体字段、更新头文件声明、帧率统计调用点以及延时逻辑中的计时与等待方式。

Changes

计时函数重构

Layer / File(s)	Summary
公共声明与结构体成员移除 src/ege_head.h, src/ege_time.h	从 _graph_setting 移除 LARGE_INTEGER get_highfeq_time_start 成员；将 get_highfeq_time_ls 声明改为无参版本并移除 _graph_setting 前置声明。
计时实现与延时调用更新 src/time.cpp	新增 <chrono>/<thread>；将 get_highfeq_time_ls 重写为基于 steady_clock 的无参实现；ege_sleep、delay_ms、delay_fps、delay_jfps 的计时与等待逻辑改为无参调用，并将 Sleep(0) 改为 yield。
帧率统计调用点更新 src/egegapi.cpp	updateFrameRate 中的 currentTime 初始化改为无参 get_highfeq_time_ls()。

旧指针悄悄不再用；
chrono 轻步向前跳，
yield 与 sleep_for 同行；
秒针落在静起点，
代码清爽咕噜噜转。

Inline comments:
In `@src/time.cpp`:
- Around line 185-189: The timing baseline in the time utility uses
high_resolution_clock, which may not be monotonic and can break
delay_fps/delay_jfps behavior if system time changes. Update the logic in the
time-related function that defines start_time_point and computes durationTime to
use std::chrono::steady_clock consistently for both the stored start point and
the current timestamp, so frame pacing and FPS measurements are based on a
stable clock.
