Dynamic Panel - Introduce an API to modify an array of a dynamic panel's footer actions

[JaneSjs]

In the following ticket, it's required to remove the Next and Previous actions from a Dynamic Panel's footer.
T20634 - Dynamic Panel in Tab mode - Customize the footer actions and hide the Next/Prev actions

Currently, this can be done using the following code:

const dynamicPanel = survey.getQuestionByName("vacation-info");
const footerToolbar = dynamicPanel.footerToolbar;
const prevAction = footerToolbar.getActionById("sv-pd-prev-btn");
const prevActionIndex = footerToolbar.actions.indexOf(prevAction);
footerToolbar.actions.splice(prevActionIndex, 1);

const nextAction = footerToolbar.getActionById("sv-pd-next-btn");
const nextActionIndex = footerToolbar.actions.indexOf(nextAction);
footerToolbar.actions.splice(nextActionIndex, 1);
