feat(Table): update auto-fit column width callback to include width

[AApuci]

Modified the OnAutoFitContentAsync callback to accept the calculated column width as a parameter in both C# and JavaScript. This allows custom logic to consider the current width when determining the final column width, improving flexibility for auto-fit scenarios.

Summary by Sourcery

Enhance the auto-fit column width feature by passing the calculated width into the user callback and refining the width computation logic in JavaScript.

Enhancements:

• Update C# OnAutoFitContentAsync signature to Func<string, float, Task> to accept the calculated column width
• Modify the JS auto-fit routine to compute max cell width (including header rows) before invoking the callback
• Invoke the callback with both field name and calculated width, and only apply the returned width if it’s positive
• Expand the JS row selector to include header rows in the auto-fit width calculation

Reviewer's Guide

This PR refines the auto-fit column width workflow by first measuring the raw maximum cell width in JavaScript, then passing that value into the C# callback for custom adjustment; it also fixes row selection to include header rows per issue #6864.
