Download kotlin-compiler-2.4.0.jar, kotlin-compiler-embeddable-2.4.0.jar,
and kotlin-stdlib-2.4.0.jar from Maven Central. Add 2.4.0 to the VERSIONS
list and update MODULE.bazel via bazel mod tidy.
The extractor does not yet compile against 2.4.0 due to removed APIs
(valueParameters, extensionReceiverParameter, getValueArgument, etc.).
Version-specific compatibility shims are needed.

Also removed the version check step, as a version not existing will give
a 404 any way later on, and that was adding a delay.
The cache is stored in a `.kotlinc_zips` and will be cleaned up by
`--clear`.
Those have shown to cause problems with too many concurrent downloads.
This changes kotlinc dependencies fetching to:
* use `resource/kotlinc-dependencies` if available (which is the case
for the internal repo)
* otherwise, download them from maven.
This means sha256 hashes need to be written down for bazel.
