[BUG] <title>Android 16 16 KB page size support for libSkiaSharp.so

[baharvipin]

Description

Description
Google Play now requires all 64-bit native libraries to use 16 KB memory page size starting with Android 16+. Currently, libSkiaSharp.so included in SkiaSharp.NativeAssets.Android v2.88.6 has a 4 KB page size, which prevents apps from targeting Android 16+.

Steps to reproduce

1. Create a .NET MAUI Android app targeting Android 16.
2. Build AAB using current SkiaSharp (v2.88.6) / MAUI workload.
3. Run page size check on .so files.
4. libSkiaSharp.so shows 4 KB page size.

Expected behavior
libSkiaSharp.so should be built with 16 KB page size to comply with Android 16+ requirements.

Environment

• SkiaSharp.NativeAssets.Android v2.88.6
• .NET MAUI 9.0
• Android 16+ target
