CI - enforce lint and type checks for benchmarks

[pavoljuhas]

• check/pylint - enforce pylint for benchmarks

• pylint - add missing copyright notice

• check/mypy - enforce type check for benchmarks

• Skip type-check for ASV benchmark scripts
  Not worth fixing as these will be replaced by pytest-benchmark-s.
