Add ability to pass environment variables to tested lambda

Example

use com\amazon\aws\lambda\Handler;

class Env extends Handler {

  /** @return com.amazon.aws.lambda.Lambda|callable */
  public function target() {
    return fn($event, $context) => sprintf(
      'Hello %s',
      $this->environment->variable('PROFILE') ?? 'default'
    );
  }
}

Invoking the lambda without passing the variable:

$ xp lambda test Env
START RequestId: 79bffe4e-226d-147a-c36a-7de3135248e8 Version: $LATEST
END RequestId: 79bffe4e-226d-147a-c36a-7de3135248e8
REPORT RequestId: 79bffe4e-226d-147a-c36a-7de3135248e8  Init Duration: 64.10 ms Duration: 4.78 ms...

"Hello default"

Passing the environment variable including a value:

$ xp lambda test -e PROFILE=testing Env
START RequestId: e51c92b4-e994-13ac-047a-e10ca56eced0 Version: $LATEST
END RequestId: e51c92b4-e994-13ac-047a-e10ca56eced0
REPORT RequestId: e51c92b4-e994-13ac-047a-e10ca56eced0  Init Duration: 52.45 ms Duration: 4.01 ms...

"Hello testing"

Passing the environment variable:

$ export PROFILE=testing
$ xp lambda test -e PROFILE Env
START RequestId: dab53651-6c21-1bab-7fa0-f62b7ef488fa Version: $LATEST
END RequestId: dab53651-6c21-1bab-7fa0-f62b7ef488fa
REPORT RequestId: dab53651-6c21-1bab-7fa0-f62b7ef488fa  Init Duration: 54.69 ms Duration: 3.98 ms...
