Fix AUTOMOC and friends to run only once the tools are built
While building on macOS, AUTOMOC sometimes hanged indefinitely.
The problem was that AUTOMOC was executed for the qmacstyle
plugin before moc was actually built.
Because of an upstream bug in CMake, AUTOMOC was caught in a deadlock
without reporting that spawning the moc process failed. Specifically
if a libuv spawn() call failed, the condition variable for a waiting
thread was not notified, and the thread kept waiting forever for the
process launch to finish.
Fix the dependency by setting the AUTOGEN_TARGET_DEPENDS property
on all targets that have AUTOGEN tools enabled. This makes sure that
moc and friends are built before they are used.
Also add some special cases to disable autogen tools on certain targets
to break cycles between targets.
Fixes: QTBUG-74636
