Merge #17480: test: add unit test for non-standard txs with too large scriptSig
5e8a56348b5e1026e9ddcae0b2fa2a68faf4439e 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.
