qml, refactoring: Separate guiconstants from QT

Separating guiconstants.h file from QT, copying it from src/qt to
src/qml and updating QAPP_APP_NAME_* constants values so Bitcoin*.conf
files with same name currently in both QT and QML gui apps don't clash
with each other (e.g. configuration file for QT on signet will be still
named as Bitcoin-Qt-signet.conf, as of today, while QML will start using
a separate file named Bitcoin-Qml-signet.conf).

This could be a temporary fix so instances from both QT and QML gui apps
don't interfere between them during QML development. This change will be
transparent for both QT app and users.
