Enable OpenSSL master branch tests for pull requests

Modified CI workflow to run tests against OpenSSL master (development) branch on pull requests in addition to scheduled runs. This enables testing compatibility with upcoming OpenSSL 4.x which removes the Engine API.

Tests enabled:
- gcc-openssl-master
- macos-openssl-master
- gcc-asan-openssl-master
- macos-asan-openssl-master
