chore: optimise first evaluation by adding worker scope cache (CE) (#38068)

## Description
- Add evalContextCache to reduce the number of times the evalContext is created from the contextTree
- remove resetWorkerGlobalScope execution before every evalSync
- Instantiate the evalWorker in src/index.tsx


Fixes #`Issue Number`  
_or_  
Fixes `Issue URL`
> [!WARNING]  
> _If no issue exists, please create an issue first, and check with the
maintainers if the issue is valid._

## Summary by CodeRabbit

- **New Features**
- Introduced a new property `actionNames` to enhance action tracking
within JavaScript action entities.
- Added a new feature flag `release_evaluation_scope_cache` for improved
feature management.
- Implemented a new function `isPropertyAnEntityAction` to identify
action properties in JavaScript entities.
- Enhanced the `loadAppEntities` method to improve JavaScript library
loading processes.
- Updated the evaluation context initialization process to utilize
`getDataTreeContext`.
- Expanded the `WIDGET_CONFIG_MAP` to include detailed configurations
for various widget types.

- **Bug Fixes**
- Enhanced error handling for unsafe function calls in evaluation logic.
- Improved error handling and logging for library installation and
uninstallation processes.

- **Tests**
- Expanded test coverage for action bindings and dependencies in the
`DataTreeEvaluator`.
- Updated tests to validate the new `actionNames` property and its
integration.
- Modified tests to ensure correct functionality of the `evaluateSync`
function.
- Added new test cases to assess the behavior of the evaluator with
widget updates.

- **Chores**
- Streamlined imports and initialization of worker instances across
various files.
