Merge #17480: test: add unit test for non-standard txs with too large scriptSig

5e8a56348b test: add unit test for non-standard txs with too large scriptSig (Sebastian Falbesoner)

Pull request description:

  Approaches the first missing test of issue #17394: Checks that the function `IsStandardTx()` returns rejection reason `"scriptsig-size"` if any one the inputs' scriptSig is larger than 1650 bytes.
