[6.x] Backport #33323 to 6.x

[rodrigopedra]

This PR is a backport from PR #33323 to the 6.x branch

The goal is to allow to report a reportable exception with the default handler by simply returning false from the report method.

The backport suggestion was made by issue #37213 where the issue's author noted if an error happens when rendering a blade view, and no dev dependencies are installed (e.g. in production), the error does not get logged to the log file.

I tested in a local installation and now it does.

One difference from PR #33323 is that in Laravel 6.x, a value returned from a reportable exception's report method is returned:

if (Reflector::isCallable($reportCallable = [$e, 'report'])) {
    return $this->container->call($reportCallable);
}

So to avoid breaking changes for developers expecting such behavior, I still return the returned value, unless it is false

if (Reflector::isCallable($reportCallable = [$e, 'report'])) {
    if (($response = $this->container->call($reportCallable)) !== false) {
        return $response;
    }
}

If the developer is manually calling the Exception handler report method and expecting false, this would be a breaking change.

But as the docblock states the report method return value should be void, I guess it is very unlikely someone is using the report handler this way.

Let me know if you prefer to change it to be the same as #33323 and I will change the PR to it.
