Build: Don't disable incremental compilation for CI

Using different incremental setting for KotlinCompile makes impossible
using caches built on CI since it is marked as @Input. Same property for
JavaCompile marked as @Internal.
We do clean checkout now so it shouldn't matter but we want to build
incrementally in some cases for Dev builds on CI.
