Add a flag to allow unbundled builds to build SDKs from source
Mainline modules are tightly coupled to the platform, and should
build against the current SDK from source and not prebuilts. Add
a flag UNBUNDLED_BUILD_SDKS_FROM_SOURCE to specify that a
TARGET_BUILD_APPS build should build the current SDK instead of
using the prebuilts.
