Dynamic dependencies have a significant impact on application startup time

[lhak]

Describe the bug

Looking at startup time of winui applications, I noticed that using dynamic dependencies for unpackaged apps has a significant impact. Compared to using appsdk self contained deployment, using dynamic dependencies increases startup time by 100-300ms depending on processor speed.

Interestingly, using the Windows functions TryCreatePackageDependency() and AddPackageDependency() for the appsdk runtime package results in a lot better performance. So I guess improvements should be possible here.

Steps to reproduce the bug

Use https://github.com/jonathanpeppers/measure-startup to measure the startup time of unpackaged apps with and without appsdk self contained deployment enabled.
