Description

This PR refactors the debug count/-popup to be able to format large numbers and data sizes properly. The following changes were made in the commits:

• Moved implementation of the methods to the cpp file.
• Added DebugCount::Flag(s) and DebugCount::configure(name, flags).
• Moved from QMap to std::map (order is important here).
• Used QStringBuilder for concatenations.
• Used QLocale for formatting (adds separators).
• Added DebugCount::Flag::DataSize for data sizes in bytes (and fixed language to English).
• Used DataSize for image sizes (maybe this should be moved somewhere else?).
• Added copy button to popup.
• Fixed Image usage reporting being eight times too large (could be another PR, but honestly it's four characters).
