New benchmarks for parsing dates with dayfirst=True and format='%d-%m-%Y'
- [x] closes #25848
- [x] tests added
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`

Gap in performance between use dayfirst or format is acceptable now.

`asv run -E existing -b ParseDateComparison -a warmup_time=2 -a sample_time=2`:
