ENH: Adding DataFrame plotting benchmarks for large datasets

[shadnikn]

• [ ] 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.
