Update the way we used to check for mcus
project in McuSupport plugin. The old way
relied on the deployment step which is only
available when the user has already added a
valid QtForMcus package to "Devices->MCU".
The addition of "isQtForMcusProject" in
externaldependenciesinterface.h will be
used in a follow-up patch in
qt-creator/tqtc-plugin-qtquickdesigner
which adds a warning when using .qtbridge
for Mcu project.
