starting maui migration

[tuke307]

:sparkles: What kind of change does this PR introduce? (Bug fix, feature, docs update...)

Hello material fans, I started the Maui migration process and updated the project. This is not a final solution! Some things are still under development and need to get fixed! I will continue working it, but I need some help. Except UWP, every project can be built. The Android sample is starting but not showing the views.

:arrow_heading_down: What is the current behavior?

no Maui support

:new: What is the new behavior (if this is a feature change)?

Maui support

:boom: Does this PR introduce a breaking change?

Yes

What I have done

• completely removed Xamarin.Forms and added Microsoft.Maui namespaces
• renamed internal .Forms namespaces to .Maui
• replaced Rg.Plugins.Popup with a Maui community version Mopups) which only works for Android and iOS
• because Color.Default does not exist anymore, i replaced it with null
• updated nugets: Roslynator.Analyzers, AsyncFixer, IDisposableAnalyzers, Microsoft.Toolkit.Uwp.UI.Controls, Autofac
• implemented the new OnPlatform structure
• updated the Readme to the current status
• replaced Color.FromHex with Color.FromArgb
• adding braces to the Color.IsDefault, because its now a method
• static Colors (Yellow, Transparent, ...) are now Color.***
• added explicit conversation from hardcoded double values to float
• changed nfloat to System.Runtime.InteropServices.NFloat
• added a blank line in each .cs file which didn't hadone yet (automatic vs setting)
• replaced TypeConversion with TypeConverter
• IList.Foreach() isn't working anymore, replaced with foreach()
• removed Vapolia.Xamarin.Svg.Forms but didn't replaced it yet

consider/not working

UWP

• don't load the MaterialMvvmSample.Uwp project (UWP is not supported yet)
• i haven't really touched the XF.Material.Plattforms.UWP stuff, consider that

Lottie

• Lottie Animations are not working yet! I am working on implementing SkiaSharp.Extended because LottieXamarin is not upgraded to Maui I commented every lottie stuff (MaterialCircularLoadingView not working for now)

Android

• Android .SetStatusBarColor don't exist anymore
• Android ViewGroup cant be accessed anymore

Image Source

• button image source not filled in samples
• because I removed Vapolia.Xamarin.Svg.Forms the svg-displaying don't work in the sample project I am working on implementing the native Image

(open the TODO list in VS to see this list)
