Adds UwpTool.install and UwpTool.uninstall methods. Refactors the
PowerShell-based install code to move the powershell-related bits out of
the Device class and into UwpTool so that when we swap out the
PowerShell-based install for the uwptool-based install, it's transparent
to the WindowsUWPDevice class.

Adds implementations for:
* WindowsUWPDevice.isAppInstalled
* WindowsUWPDevice.uninstallApp

Refactors:

Allow flutter run to work end-to-end with a UWP device.

Uses win32/ffi for the actual launch of the application, injected via
the native API class. This is structured to avoid a g3 dependency.

Install and amuid require powershell scripts for now.

Actually connecting to the observatory requires running a command in an
elevated prompt. Instructions are presented to the user if a terminal is
attached.

This is a rebased version of https://github.com/flutter/flutter/pull/79684
by @jonahwilliams, updated to remove `NativeApi` and replace is with calls
to `uwptool`.
