[TIMOB-27167] CLI: Move Alloy optimizations into core SDK build

Alloy does some additional work in specialized Babel plugins to "optimize" Alloy applications. But most of these can be generally useful for Titanium apps and should be moved into the mainline build process to benefit all apps (and to simplify Alloy's build process which is poorly written resulting in some hard to fix build/source map bugs and performance issues). Specifically Alloy allows developers to make use of special references that get replaced by true/false: - OS_IOS, OS_ANDROID, OS_WINDOWS - ENV_DEV, ENV_DEVELOPMENT, ENV_TEST, ENV_PROD, ENV_PRODUCTION - DIST_ADHOC, DIST_STORE Then it strips out dead code as a result (because these are typically use in if/else guards for platform-specific code)
