[flutter_local_notifications_windows] add runtimeobject.lib to resolve unresolved WinRT symbols (MaikuB#2650)

Sebastien-VZN · web-flow · commit 13f25b516809 · 2025-07-11T23:03:57.000+10:00
Without this, Windows builds fail with unresolved external symbol errors
related to WINRT_IMPL_RoGetActivationFactory and RoOriginateLanguageException.

This links the missing `runtimeobject.lib` explicitly as required by MSVC
since newer Windows SDKs no longer link it implicitly.

Tested on:
- Windows 11 + MSVC 2022
- Flutter stable 3.32.6
