[Shell] Fix query parsing and allow more types for parameters

[PureWeen]

Description of Change

• if the destination type isn't a string try to convert it to property type
• if the parameter is a string url decode it before passing it into the destination
• Fix an issue where url's passed as parameters was removing too many "/"

Issues Resolved

• fixes [Bug] [Shell] Navigation URL parameter not correctly encoded/decoded #10899

Platforms Affected

• Core/XAML (all platforms)

Behavioral/Visual Changes

• This code will url decode the parameter before passed to the VM so the behavior is slightly different. But if the user was already decoding then their decode should be a noop

Testing Procedure

• unit tests included

PR Checklist

• Targets the correct branch
• Tests are passing (or failures are unrelated)

can we make ApplyQueryAttributes public? :)

[PureWeen]

@rmarinho I think ApplyQueryAttributes is going to go through some changes so probably not now

Tested here on my side, and everything works like a charm

How do I pass an object (lets a instance of a class or a custom property "Foo") via query params? Some examples would be nice please :)
