Allow interrupting tasks in repl with Ctrl+C
## What changes were proposed in this pull request?
Improve signal handling to allow interrupting running tasks from the REPL
(with Ctrl+C).
If no tasks are running or Ctrl+C is pressed twice, the signal is forwarded
to the default handler resulting in the usual termination of the application.
This PR is a rewrite of -- and therefore closes #8216 -- as per
@piaozhexiu's request
## How was this patch tested?
Signal handling is not easily testable therefore no unit tests were added.
Nevertheless, the new functionality is implemented in a best-effort approach,
soft-failing in case signals aren't available on a specific OS.
