When building examples as part of Qt in the CI, it's best to skip
running deployment for all examples to save resources
(space and time).
Add a QT_DEPLOY_MINIMAL_EXAMPLES option similar to our
QT_BUILD_MINIMAL_STATIC_TESTS option, which will set
QT_INTERNAL_SKIP_DEPLOYMENT at the root examples directory scope, to
skip deployment for all examples.
Each example can then opt into the minimal subset by unsetting the
QT_INTERNAL_SKIP_DEPLOYMENT variable before its
qt_internal_add_example call.
Add Coin instructions to enable this option when building our examples
in the CI.
