8f2d7737cc236b6122f30e31856eb3181960fba1 test: add functional test for non-standard txs with too large scriptSig (Sebastian Falbesoner)

Pull request description:

  Approaches another missing functional test of issue #17394 (counterpart to unit test in PR #17480, Commit 5e8a56348b): A transaction is rejected by the mempool with reason `"scriptsig-size"` if any of the inputs' scriptSig is larger than 1650 bytes.
