[🚀esl-panel-group]: add ability to specify the strategy of closing panels in case the `max-open-items` limit is reached

[ala-n]

As an ESL consumer, I want to have a predictable and full strategy for esl-panel-group in case it handles max-open-items (more than 1 panel).

Test case:

• Configure 4 esl-panels inside of esl-panel-group
• Set esl-panel-group limit max-open-items = "3"
• Make open 2-d, 3-rd and 4-th panel
• Try to open 1-panel, repeat reopening of invective panel

Current behavior: Only 1-st and 2-nd panels can be closed.

Expected behavior: Strategy to close active panels according to some order, ideally predictable.

Considered solutions:

1. Implement a round counter to choose an active panel to close
   • needs to be implemented in POC, not sure it doable with one simple counter
2. Math random

• the easiest way, 100% doable, but unpredictable

3. Some other suggestions....
