feat(bar_chart): Stacked Bar chart with Time comparison in separated stacks

[Antonio-RiveroMartnez]

SUMMARY

When using the bar chart in stacked mode, the time comparison series are displayed on top of the original ones, making the chart render just one bar with all series.

This PR separates each time compare if any into its own stack so users can properly visualize the comparison data vs original ones.
