Mosa.Utility.Launcher: Code style changes

[AnErrupTion]

Hello! This PR makes code style changes throughout the Mosa.Utility.Launcher project in order to improve consistency with other projects. The following changes were done:

• The space shift when putting braces after a case statement has now been removed as a ReSharper rule
• Code after a statement (like if) was put on a separate line if not already the case
• Method bodies were transformed into expression bodies whenever possible
• Null-coalescing operators were used whenever possible
• Braces around statements were removed if the containing block had only 1 line of code
• Commented code was removed
• Variables whose name didn't give any more useful insight into what it is were inlined (e.g. var arg = "convert -f raw [...]";)
• Strings that were too long (like in Builder.GetLimineCFG()) were transformed into multi-line strings
• Using blocks were transformed into using statements whenever possible
• If statements were transformed into 1 switch statement whenever it made sense (when there are more than 2 if statements)
• Private fields were moved after public fields
• Patterns were used in comparisons whenever possible
• Ternary operators were used whenever it made sense for cleaner code
