R&D: XML (*.qrc) support in qrc! macro

[ratijas]

This is a tracking issue for a planned Research & Development activity.

Tasks

Investigate the source code and documentation of Resource Compiler (rcc) tool from Qt. Can the qrc! implementation be extended to support XML resource files (*.qrc)? Which other features of the rcc tool can be ported into the qrc! macro?

Why?

I could think of two main reasons where you would want to use XML .qrc resource file:

1. Reuse already existing XML. Rewriting it into Rust "native" macro syntax just because you can? Nah, leave it for RESF.
2. Interoperability with Qt Creator. Qt Creator doesn't like it when QML files are just lying around. Providing a qrc definition improves its navigation, code insights etc.
