https://github.com/google/wycheproof provides test vectors exposing vulnerabilities in crypto packages. This change creates a new package called internal/wycheproof that runs these Wycheproof tests against a number of pacakages in the standard library (and in the future, x/crypto). Directory structure: - interal/wycheproof/internal/ecdsa: internal version of ecdsa package which includes a new function that verifies ASN encoded signatures directly - interal/wycheproof/internal/dsa: internal version of dsa package which includes a new function that verifies ASN encoded signatures directly - internal/wycheproof: all tests internal/wycheproof/wycheproof_test.go provides utility functions that are common to many tests in the package, and contains the TestMain which fetches github.com/google/wycheproof from the source. This change includes tests for signature verification with dsa, ecdsa, eddsa, and rsa (both PKCS#1 v1.5 and PSS signatures). Note that these tests download testdata from github.com/google/wycheproof by running `go mod download` in the TestMain. This means that internet access will be necessary in order to run these tests if the testdata is not already in your module cache. More tests will be added incrementally.

This package runs a set of the Wycheproof tests provided by https://github.com/google/wycheproof.
The JSON test files live in https://github.com/google/wycheproof/tree/master/testvectors and are being fetched and cached at a pinned version every time these tests are run. To change the version of the wycheproof repository that is being used for testing, update wycheproofModVer.
The structs for these tests are generated from the schemas provided in https://github.com/google/wycheproof/tree/master/schemas using https://github.com/a-h/generate.
