feat(slider): add tick alignment support for Slider component

Add alignToTicks property to Slider, allowing the groove to align with
tick marks when enabled. The groove drawing is offset by half the handle
width on both ends when alignToTicks is true.

为 Slider 组件添加 alignToTicks 属性，支持滑块槽与刻度标记对齐。
启用时，槽的绘制会在两端偏移半个手柄宽度。

Log: 添加 Slider 刻度对齐功能
PMS: BUG-275271
Influence: 当 TipsSlider 有刻度时，滑块槽会自动与刻度对齐，提升视觉效果。
