Fix tick label overflow between sm panels

[nickofthyme]

Describe the bug
When dimensioning small multiple panels, each panel is treated as one small panel instead of Individually. This means that any tick labels that overflow into the nearest panels may not be corrected for and cause labels to overlap.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://elastic.github.io/elastic-charts/?path=/story/small-multiples-alpha--grid-lines
2. Slowly drag the right-hand panel to make the chart smaller.
3. Notice the ticks get closer and closer and eventually overlap

Expected behaviour
The tick labels should not overlap between panels

Version (please complete the following information):

• Elastic Charts: latest

Additional context
Related to #891 and #397

I'm not sure if this could be solved when we decide to improve the label logic to be more robust and filter values more intuitively.
