Fix 14062: Exclude sizing grip width from DisplayRectangle when SizingGrip is enabled

[LeafShi1]

Fixes #14062

Proposed changes

• Override StatusStrip.DisplayRectangle When SizingGrip == true:
  • Compute DPI-scaled grip width via ScaleHelper.ScaleToDpi(GripWidth, DeviceDpi).
  • If RightToLeft == Yes, subtract width from the left and shift rect.X to the right by the grip width.
  • If RightToLeft == No, subtract width from the right side.
  • Use Math.Max(0, …) to guarantee non-negative width.

Customer Impact

• When SizingGrip is enabled, the text of the ToolStripStatusLabel at the end no longer overlaps with or is truncated by the grip, especially when mixed with labels set to Spring = true, resulting in greater stability.

Regression?

• Yes

Risk

• Minimal

Screenshots

Before

The right label is missing when the first ToolStripStatusLabel has Spring = True

After

The right-side label is displayed in full.

Pull Request Overview

This PR fixes issue #14062 by overriding the DisplayRectangle property in StatusStrip to properly exclude the sizing grip width when SizingGrip is enabled. This prevents ToolStripStatusLabel items from overlapping with or being truncated by the grip, especially when using Spring = true.

Key changes:

• Override DisplayRectangle property to reduce available space by the DPI-scaled grip width when SizingGrip is enabled
• Handle RTL layouts by adjusting both X position and width for right-to-left, or just width for left-to-right
• Document the new public API surface in PublicAPI.Unshipped.txt
