bpf: add various test cases to selftests
Add various map value pointer related test cases to test_verifier kselftest to reflect recent changes and improve test coverage. The tests include basic masking functionality, unprivileged behavior on pointer arithmetic which goes oob, mixed bounds tests, negative unknown scalar but resulting positive offset for access and helper range, handling of arithmetic from multiple maps, various masking scenarios with subsequent map value access and others including two test cases from Jann Horn for prior fixes.
