Brian Hotopp 1081731f54 [2.x] fix: Report a missing input file clearly instead of an opaque SerializationException
When a file referenced by a task's inputs/outputs (e.g. `Compile / resources +=
file("nope.txt")`) does not exist, hashing the task's cache key threw a
NoSuchFileException deep inside sjsonnew serialization. It surfaced as an opaque
sjsonnew.SerializationException that dumped the entire input list, with the real
cause buried several `Caused by:` levels down, so users routinely mistook it for
a corrupt cache and reached for `clean`.

ActionCache.mkInput now catches the hashing failure, detects a NoSuchFileException
anywhere in the cause chain (ActionCache.findMissingFile), and throws a
MessageOnlyException naming the file:

    [error] file referenced by the build does not exist: nope.txt

util-cache gains a dependency on util-control (a leaf module, no cycle) for
MessageOnlyException.

Fixes #9217.
