playground: support examples as tests

Playground handles examples in the same way as "go test" does.

If the program contains examples and does not import the "testing"
package, the playground injects the import without changing line numbers.
This is to prevent a mismatch of highlighted error lines on the
web page. The resulting import code is not properly formatted,
but it does not have to be since it is not meant to be read by humans.

Fixes golang/go#24311
