SearchKit - Update hook_civicrm_searchKitTasks signature

[colemanw]

Overview

Update hook_civicrm_searchKitTasks signature to include checkPermissions and userId.

Before

Hook signature has 1 param.

After

Hook signature has 3 params.

Notes

It's a slightly confusing bit of code due to the dual-purpose nature of the hook - it's used both to gather an array of tasks and to get a full list of Angular modules which provide tasks. That's why this hook needs the base-level array and not just the array of tasks for $this->entity.
Although it may seem wasteful to have extensions add tasks for all possible entities and then the API discards most of it (all but the ones relevant to $this->entity), it's necessary to do it this way so that search_kit_civicrm_angularModules() can gather Angular dependencies.
