Reverts the Windows App SDK update from version 1.7 to 1.8 introduced in
PR #32174.

## Reverted Changes

**Version downgrades:**
- `MicrosoftWindowsAppSDKPackageVersion`: `1.8.251106002` →
`1.7.250909003`
- `MicrosoftWindowsSDKBuildToolsPackageVersion`: `10.0.26100.4654` →
`10.0.22621.756`

**Package references removed:**
- `Microsoft.WindowsAppSDK` from `Essentials.csproj`,
`Graphics.Skia.csproj`, `Graphics.Win2D.csproj`

**Restored configurations:**
- `Controls.Xaml.csproj`: Re-added `WINDOWS` define constant and
`AppxGeneratePriEnabled=false`
- `Directory.Build.targets`: Removed
`GetTypeScriptCopyToOutputDirectoryItems` target
- `WindowsTemplateTest.cs`: Restored original RID-based asset path logic
- `windows.cake`: Restored `X509KeyUsageFlags.NonRepudiation` in
certificate generation

This reverts commit 5a39604.
