[Task] Add build support for Application, Script, Library, Development Library package types with paket build

[eminfedar]

Description:
Create a paket regarding to the paket type of these:

• PackageType::Application
• PackageType::Script
• PackageType::Library
• PackageType::DevelopmentLibrary

Custom Fields for Types:

• PackageType::Application =>

[application]
executable = "myapp"
icon = "myapp.svg"

assets_folder = "assets" # stores the assets(image,video,sound,binary,text data etc.) in paket folder. like: assets/img/logo.png, assets/sound/intro.ogg, assets/3d_objects/My3DModel.obj
desktop_file = "assets/export/myapp.desktop" # optional, automatically generated if not provided

• PackageType::Script =>

[script]
executable = "main.py" # To create link `/usr/bin/myapp` -> `/usr/share/paketname/src/main.py`
icon = "myapp.svg"

sources_folder = "src" # stores the scripts in paket folder. like: src/main.py, src/MainWindow.py, src/Utils.py
assets_folder = "assets" # stores the assets(image,video,sound,binary,text data etc.) in paket folder. like: assets/img/logo.png, assets/sound/intro.ogg, assets/3d_objects/My3DModel.obj
desktop_file = "assets/export/myapp.desktop"  # optional, automatically generated if not provided

Acceptance Criteria:

• Local paket can be builded and created successfully.
• Different build tactics for different PackageTypes. (maybe?)
• Tests are passing.
• Documentations on every struct, property and function is written with ///. There should be a description and a small example usage.
