Bump WindowsAppSDK to 2.0.1 (#47470)

## Summary of the Pull Request

Bumps `Microsoft.WindowsAppSDK` (and split sub-packages) from
**`1.8.260209005`** to public NuGet''s **`2.0.1`** GA, plus the
centrally-pinned `Microsoft.Web.WebView2` to **`1.0.3719.77`** to
satisfy the new transitive requirement from
`Microsoft.WindowsAppSDK.WinUI 2.0.12`.

This is the minimum mechanical version-bump set required for the
WinAppSDK 2.0 upgrade ΓÇö no API migration or behavioral changes.
Subsequent commits on this branch will address breaking-change
migrations as they surface.

NuGet source-of-truth used to pick sub-package versions: WinAppSDK 2.0.1
catalog `dependencyGroup`
(https://api.nuget.org/v3/catalog0/data/2026.04.29.22.25.36/microsoft.windowsappsdk.2.0.1.json).

## Detailed Description of the Pull Request / Additional comments

### Scope

| Package | Pinned |
|---|---|
| `Microsoft.WindowsAppSDK` | `2.0.1` | 
| `Microsoft.WindowsAppSDK.Foundation` | `2.0.20` | 
| `Microsoft.WindowsAppSDK.AI` | `2.0.185` | 
| `Microsoft.WindowsAppSDK.Runtime` | `2.0.1` | 
| `Microsoft.Web.WebView2` | `1.0.3719.77` | 

## Validation Steps Performed

`tools\build\build-essentials.cmd` results on the temp branch (x64
Debug, VS 2026 Insiders 14.51.36231):

| Stage | Errors | Warnings | Time |
|---|---|---|---|
| `PowerToys.slnx` NuGet restore | **0** | 0 | 1:05 |
| Native C++ `src\runner\runner.vcxproj` | **0** | 0 | 4:08 |
| Managed `src\settings-ui\Settings.UI\PowerToys.Settings.csproj` |
**0** | 0 | 3:35 |

Exit code: **0**. The end-to-end `build-essentials` flow passes locally
ΓÇö the WinAppSDK 2.0 upgrade is verified to compile against the runner
+ Settings.UI projects.
