Darwin: Disable QMacAutoReleasePool tracker unless explicitly enabled
There's a few orders of magnitude of overhead using QMacAutoReleasePool
with the tracker enabled, so disable it even for debug builds, unless
explicit auto release pool debugging has been enabled via the environment
variable QT_DARWIN_DEBUG_AUTORELEASEPOOLS.
Pick-to: 6.5
