qml, refactoring: Separate guiconstants from QT

Saparating guiconstants.h file from QT, copying it from src/qt
to src/qml and updating QAPP_APP_NAME_* constants values so
Bitcoin*.conf don't clash with each other (e.g. configuration
file for QT on signet will be Bitcoin-Qt-signet.conf, as of today,
while QML will start a separate one 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.
