[TIMOB-15198] Fixed bug with plugins not being loaded correctly and thus Alloy not being triggered. [TIMOB-14884] Fixed bug in iOS build with the platform specific folders not being copied over top the root level files. Also included a handful of Android build related changes that should not affect the old python-based Android build.
Added back the sim-64bit flag that I accidentally deleted.
Added sudo to xcode-select warning message.
