Add GotoAsync overload for single use query parameters

[PureWeen]

Description of Change

Alternate PR from
#15281
#14965

• Add a new overload that lets user pass in a query parameter type that is only retained for the ShellNavigationQueryParameters
• No breaking changes compared to Don't retain parameters not passed as query string parameters #14965
• Slightly less weird than Obsolete Dictionary and shift to single state object #15281. This one stays within the concept of "query parameter" and feels a bit narrower of an API add to give the users what the need for NET8.

Examples for the docs to improve clarity

We should enhance the navigation part of the Shell docs to include various example permutations of how parameters are handled.

Still works the same

await GotoAsync("firstPage?param=1");
await GotoAsync("nextPage");
await GotoAsync(".."); // param = 1 will get applied to `firstPage`

New

ComplexObject obj;
var params = new ShellNavigationQueryParameters()
{
    {"field", obj}
}

await GotoAsync("firstPage?param=1", params);
await GotoAsync("nextPage");
await GotoAsync(".."); // param = 1 will get applied to `firstPage` but `ComplexObject` won't

Issues Fixed

Fixes #10294

This adds a new API. We can't backport new APIs to net7.0.
