Q_DISABLE_MOVE/COPY_MOVE; QT_IGNORE_DEPRECATIONS

DISABLE_MOVE is no more; instead, the library provides Q_DISABLE_MOVE
(and also Q_DISABLE_COPY_MOVE while at it) for Qt pre-5.13 that don't
have it yet. Same for QT_IGNORE_DEPRECATIONS - it only arrived in 5.15
but all the building pieces existed prior so libQuotient has it
regardless of the Qt version used for building.
