Consolidating buildSrc caches for cacheableApi into out/buildSrc/build
Consolidating buildSrc caches for cacheableApi into out/buildSrc/build

The configuration is the same across buildSrc subprojects so we can reuse the resolution

This reduces the time to run `find ../../out/buildSrc -name deps -o -name result | xargs rm -f && time ./gradlew :help --no-daemon --no-configuration-cache` (after two warmups) from about 13.582s to about 12.833s on my computer

Thanks to Ivan for suggesting it
