[fix-finder] Add missing `using` declarations for SKFont instances in SKFontTest

[github-actions]

Problem

SKFontTest.cs has 27 test methods that create new SKFont(...) without a using declaration, leaking the native Skia font handle when the test completes. The file already uses using var font = new SKFont() in 14 other tests, so the inconsistency is clear.

Location

• File(s): tests/Tests/SkiaSharp/SKFontTest.cs
• Line(s): 83, 112, 125, 143, 154, 164, 183, 194, 217, 229, 242, 250, 258, 276, and others

Current Code

var font = new SKFont(SKTypeface.Default);

var widths = font.GetGlyphWidths("Hello World!", out var bounds);
// ... assertions ...

Suggested Fix

using var font = new SKFont(SKTypeface.Default);

var widths = font.GetGlyphWidths("Hello World!", out var bounds);
// ... assertions ...

Apply the same pattern to all ~27 instances in this file where var font = new SKFont(...) appears without using. The fix is purely mechanical: add using before var on each declaration.

SkiaSharp Guidelines

• Does NOT modify any *.generated.cs file
• Does NOT change existing public API signatures (ABI stable)
• Does NOT use default parameters in public methods
• Does NOT use .NET 6+ APIs without #if guards
• Follows existing code style and naming conventions

Acceptance Criteria

• All var font = new SKFont(...) declarations in SKFontTest.cs use using var font = new SKFont(...)
• No test logic is changed — only the using keyword is added
• All tests pass: dotnet test tests/SkiaSharp.Tests.Console/SkiaSharp.Tests.Console.csproj
• No new warnings introduced
