Merge #20326: tests: Fix ecdsa_verify in test framework
568a1d72619371a45b14a8356d3f80bd0c0efabc fix ecdsa verify in test framework (Stepan Snigirev) Pull request description: This PR fixes a small bug in the test framework in `verify_ecdsa` function. `r` in ecdsa signature is modulo curve order, so if the point `R` calculated during verification has x-coordinate that is larger than the curve order, the verification will fail in the test framework but pass in libsecp256k1. Example (all in hex): public key: `0289d889551598a0263746c01e5882ccf9b7dc4ca5a37108482c9d80de40e0a8cf` der signature: `3006020104020104` (r = 4, s = 4) message: `3232323232323232323232323232323232323232323232323232323232323232` libsecp256k1 returns `true`, test framework returns `false`.
