Separate types for Android Resources ID's

[KirillAldashkin]

1. Create a separate struct for each type of identifier: LayoutId, ViewId, DrawableId, etc. For example:

struct ViewId // LayoutId, DrawableId, ...
{
    public int Id;
    public ViewId(int id) => Id = id;
    public static implicit operator ViewId(int id) => new(id);
}

2. Add API to use them in MAUI Android SDK. For example:

T? Android.App.Activity.FindViewById<T>(ViewId id);
void Android.App.Activity.SetContentView(LayoutId id);
Android.Views.Animations.Animation? Android.Views.Animations.AnimationUtils.LoadAnimation(Android.Content.Context? context, AnimationId id);

3. [May be breaking] Change the Resources class generator to use these structs instead of ints.

This simple change will help to avoid messing with resource ID's and make code clearier.
