Memory Leak on Page Navigation while removing the page.

[thanigaiharan]

Description

In our application Performance degradation when navigating to a page and going back several times and also the memory keeps on increasing which leads to app crash.
we have lots of CollectionViews and complex master-details with multiple views, data forms and custom controls.

1. Memory Leak on Page navigation where we will remove the Page :

 we have Fleets page where we show list of fleets in collection view. (Binding have been done in the backend .cs File of XAML).
 In the same page we have Home Icon which helps to navigate to the another page ( FleetsHome Page) .
 When navigating to the FleetsHome page we will Application.Current.MainPage.Navigation.RemovePage(FleetsPage) since we wont navigate Back to Fleets Page.
 Here When we continuolsy Navigating between pages this the the app memory increases on each navigation.

Question :

1. By Right when we call Application.Current.MainPage.Navigation.RemovePage(FleetsPage) , it should dispose the controls and resources of FleetsPage?
2. How Do we need to ensure the Page is disposed properly?

Steps to Reproduce

1. Create the .NET MAUI PROJ with 2 Pages (Register the ViewModel as AddTransient)
2. Navigate Page 1 -> Page 2 -> Page 1 (Using RemovePage() and Not Back navigation) -> Page 2. (Keep on Navigating to see memory can )
