Fill API documentation placeholders

[github-actions]

Automated AI-generated documentation for XML API docs with 'To be added.' placeholders.

Changes

Filled 817 documentation fields across 29 XML files covering:

• HarfBuzzSharp.Face — variation axis and color palette methods/properties
• HarfBuzzSharp.Font — variation coordinate methods
• SkiaSharp.GRVkYcbcrComponents / GrVkYcbcrConversionInfo — Vulkan YCbCr structs
• SkiaSharp.SKCanvas, SKSurface, SKPaint, SKPath, SKPathBuilder, SKPathMeasure, SKStream
• SkiaSharp.SKColorSpace, SKColorspacePrimariesCicp, SKColorspaceTransferFnCicp, SKColorType
• SkiaSharp.SKDocumentXpsOptions, SKFontArguments, SKFontPaletteOverride, SKFontVariationAxis, SKFontVariationPositionCoordinate, SKFourByteTag
• SkiaSharp.SKTypeface, SKWebpEncoder, SKWebpEncoderFrame
• SkiaSharp.Views.Blazor._Imports, SkiaSharp.Views.Gtk.GTKExtensions, SKDrawingArea

Review process

Documentation was written by a general-purpose agent, then reviewed by three independent agents (factual claim verifier, code example verifier, quality reviewer). Critical issues found and fixed before merge:

• GRVkYcbcrComponents remarks example: removed reference to VkComponentSwizzle (not in SkiaSharp bindings); replaced with numeric literals
• SKWebpEncoderFrame remarks example: fixed constructor calls to use correct (pixmap, TimeSpan) signature and TimeSpan.FromMilliseconds() for duration
• SKWebpEncoder remarks example: added null check before calling .ToArray() on nullable SKData? return value
