[TSVB] Y-axis has number formatting not considering all series formatters in the group

[DianaDerevyankina]

Related to #74951 and #78426

Kibana version: since 7.10

Describe the bug:
When creating multiple series the Y-axis shows simple value formatting no matter what type of formatting series in the group have.

Steps to reproduce:

1. Create a TSVB visualization
2. Create the first series and customize its format as a percent
3. Create some other series and customize its format with percent

Expected behavior:
I think it would be nice to have percent formatting for Y-axis if all the series have percent formatting too.
