Update Wycheproof multiple ECDSA test vectors to v1

[Sajjon]

Update Wycheproof ECDSA test vectors to v1. This PR updates one single unit test file: ECDSASignatureTests which contains tests for P256, P383 and P521 with different Hash Function versions. Since all curves with HashFunctions are put in the same unit test file I had to update all vectors simultaneously.

@Lukasa let me know if you prefer it I break out the each test vector file into seperate unit test files, and do one PR per test vector file.

Checklist

• I've run tests to see all new and existing tests pass
• I've followed the code style of the rest of the project
• I've read the Contribution Guidelines
• I've updated the documentation if necessary

If you've made changes to gyb files

• I've run .script/generate_boilerplate_files_with_gyb and included updated generated files in a commit of this pull request

Motivation:

We ought to use as many and as up to date test vectors as possible. Wycheproofs v0 were created 4 years ago and were due some upgrade.

Modifications:

The following Wycheproof test vectors have been updated:

• ecdsa_secp256r1_sha256_test.json
• ecdsa_secp256r1_sha512_test.json
• ecdsa_secp384r1_sha384_test.json
• ecdsa_secp384r1_sha512_test.json
• ecdsa_secp521r1_sha512_test.json

The following unit test file have been updated ECDSASignatureTests.swift, with a trivial JSON key change: key -> publicKey.

Result:

Many more tests are run.
