Jiří Polášek 14a966f3ee CmdPal: Add file and list settings controls (#49623)
## Summary of the Pull Request

This PR adds reusable Command Palette extension settings controls for
selecting files and folders and managing lists.

The new controls include:

- `FilePathSetting` for selecting a single file or folder.
- `FilePathListSetting` for managing multiple file and/or folder paths.
- `StringListSetting` for managing plain string values.
- `KeyValueListSetting` for managing key-value pairs.
- Optional regex validation for strings, keys, and values.
- Optional duplicate prevention for strings and key-value keys.
- Configurable file picker filters.
- Custom persisted-string conversion.
- Fallback content when the Command Palette host does not support a
control. But this has no direct impact now, because there's a bug in
WinUI3 AC renderer that throws it away (sad panda).

## Pictures? Picture!

## Detailed Description of the Pull Request / Additional comments

This PR extends `Microsoft.CommandPalette.Extensions.Toolkit` with
file-path, file-path-list, string-list, and key-value-list settings.

The Command Palette host registers custom Adaptive Card input elements
during application startup. The controls use native file and folder
pickers parented to the window containing the form, so they work
correctly in both the Settings window and palette-hosted forms.

List controls render as constrained, scrollable lists with add and
remove actions. They support developer-configurable validation,
duplicate handling, picker modes, and error messages.

List values crossing the extension/host boundary use a structured codec
that preserves unknown properties and remains compatible with the
previously accepted bare-string representation. Persisted values can use
the default newline representation or developer-provided conversion
callbacks.

The SDK emits Adaptive Card `requires` and fallback information so
extensions built with the new controls can provide actionable content
when loaded by an older Command Palette host.

A Sample Pages extension page demonstrates all new setting types and
their validation options.

<!-- Describe how you validated the behavior. Add automated tests
wherever possible, but list manual validation steps taken as well -->
