Daniel Chao 1cc20b611f Revert configuration cache (#1659)
This reverts the commits that enabled Gradle's configuration cache
feature.

IMO: this feature is too hard to use. We don't know if a task is valid
for the configuration cache until it runs, and it's very hard to tell if
something is safe when authoring Gradle code.
For example, our publish tasks are currently failing; I don't know how I
would fix this without running the publish task again on my dev machine.

Also, some of our build scripts become more brittle because of this; for
example, see
https://github.com/apple/pkl/blob/bb07589eae0b3195a589559a3245cbc12c29b394/build-logic/src/main/kotlin/BuildInfo.kt#L291-L296
