Gradle: various updates to support more closed build options and tasks

1) Added several new build tasks: apps, findbugs, publicExports [*], perf [*], zips [*], all (everything but tests), fullTest

[*] - closed only

2) Support a new -PBUILD_CLOSED=true command line property as a convenient alternative to specifying a closed build located as "../rt-closed" (default=false)
