ENH: Adding DataFrame plotting benchmarks for large datasets
- [ ] related to #61532  - Adding in performance benchmarks for DataFrame plotting with large datasets.
- [ ] Description: Added 'DataFramePlottingLarge' benchmark class to track performance issues related to bottlenecks in #61398 and #61532. Tests multiple DataFrame sizes with/w/o DatetimeIndex & provides a baseline single-column comparison.
- [ ] Intended to cover:
          - DataFrame sizes: (1000,10) to (10000,10)
          - DatetimeIndex vs. regular index comparison
          - Multi-column vs. single-column plotting.

@rhshadrach do you have an opinion about this? @shadnikn - what is the runtime of these benchmarks on your machine? Thanks for the pull request, but it appears to have gone stale. If interested in continuing, please merge in the main branch, address any review comments and/or failing tests, and we can reopen.
