[Windows] Filenames contain `uwp` even though UWP is not the technology used

[MartyIX]

Description

When contributors see files like

• https://github.com/dotnet/maui/blob/main/src/Essentials/src/Compass/Compass.uwp.cs
• https://github.com/dotnet/maui/blob/main/src/Essentials/src/TextToSpeech/TextToSpeech.uwp.cs
• etc.

they can easily thing that the code uses Universal Windows Platform (UWP). However, this is not true because .NET MAUI utilizes WindowsAppSDK which is a successor of UWP. Given that these two platforms are quite similar but differs in things like namespaces¹, it's easy to confuse one for other.

Consider renaming files to reflect the current state of affairs.
