Add RegExp recursion depth limit (#2543)

The regexp engine does not have any recursion depth check, thus it can cause problems with various regexps. Added a new build option `--regexp-recursion-limit N` whose default value is 0, which is for unlimited recursion depth. Also added a build-option-test. Fixes #2448 Fixes #2190 JerryScript-DCO-1.0-Signed-off-by: Istvan Miklos imiklos2@inf.u-szeged.hu
