Code Quality: Correct namespaces

[0x5bfa]

Description

I'd like to work on #4180 by reorganizing namespaces and I'd like you guys to feedback one by one whether it is able to be implemented.

Summary

0. Correct those namespaces in Files.App

Change models:

'Views/SettingsPages/*.xaml(.cs)'        ->   'Views/Settings/*Page.xaml(.cs)'
'Views/Pages/Properties*.xaml(.cs)'      ->   'Views/Properties/*Page.xaml(.cs)'
'ViewModels/Properties/*Properties.cs'   ->   'ViewModels/Properties/*ViewModel.cs'
'ViewModels/SettingsViewModels/*.cs'     ->   'ViewModels/Settings/*.cs'
'ViewModels/Dialogs/*DialogViewModel.cs' ->   'ViewModels/Dialogs/*ViewModel.cs'

Preview samples:

'Views/SettingsPages/Appearance.xaml'   ->   'Views/Settings/AppearancePage.xaml'
'Views/Pages/PropertiesSecurity.xaml'   ->   'Views/Properties/SecurityPage.xaml'
'ViewModels/SettingsViewModels/AppearanceViewModel.cs' -> 'ViewModels/Settings/AppearanceViewModel.cs'
'ViewModels/Properties/SecurityProperties.cs'          -> 'ViewModels/Properties/SecurityViewModel.cs'
'ViewModels/Dialogs/CreateShortcutDialogViewModel.cs'  -> 'ViewModels/Dialogs/CreateShortcutViewModel.cs'

1. Merge 'Files.Backend' and 'Files.Shared' into 'Files.Core' (, which is new)

• Files.Backend -> Files.Core
• Files.Shared -> Files.Core (merge into Core)

5. Move 'Files.App.CommandLine'

• Files.App.CommandLine -> Files.Core.CommandLine

6. Move UI-unrelated 'Files.App.Helpers' and 'Files.App.Extensions'

• Files.App.Helpers -> Files.Core.Helpers
• Files.App.Extensions -> Files.Core.Extensions

7. Merge 'Files.App.AppModels' into 'DataModels' (, which is existing already)

• Files.App.AppModels -> Files.App.DataModels

8. Merge 'Files.App.ValueConverters' into 'Files.App.Converters' (, which is existing already)

• Files.App.ValueConverters -> Files.App.Converters

Concerned code

Not codes but namespaces.

Gains

• A better accessible/predictable namespaces.

Requirements

• Rename those with VS 2022 search/replace functionality.

This looks good, do you want to implement?

4. Rename 'Files.App (Package)' with 'Files.Package'

This will break our build process so not this one.

@d2dyno1 can you answer the rest?

[d2dyno1]

I wanted to separate the backed from Shared project. This way we can share common code like utilities and extensions between multiple projects

Why did you though they should be separated?

I think there's no problem(there's no reason to do that) and no code decrease maintainability even if they are in the same namespace.
