ci: run performance tests

Performance tests added to perf directory are not automated and
currently we run these tests manually from time to time. From other side
source code that used rarely could lead to software rot [1].

The patch adds CMake target "test-perf" and GitHub workflow, that runs
these tests in CI. Workflow is based on workflow release.yml, it builds
performance tests and runs them.
