Enable Gradle configuration cache for faster builds

Enables Gradle's configuration cache to significantly improve build
performance on subsequent builds by caching the result of the
configuration phase. Set to warning mode to accommodate the
net.researchgate.release plugin which isn't fully compatible yet,
while still providing performance benefits for most build tasks.
