[Security Solution] Add skipped rules to Bulk Edit rules API response (…

…#147345)

**Addresses:** #145093
**Related to:** #139802

## Summary

- Extends Bulk Edit API to return a new `skipped` property for rules
whose updating was skipped. See
[#145093](#145093) for details
on when a rule is skipped.
- In `x-pack/plugins/alerting/server/rules_client/methods/bulk_edit.ts`,
refactored the methods `bulkEdit` and `bulkEditOcc` to smaller methods,
following an immutable approach.
- Updated all related tests and expanded coverage. (unit, integration
and e2e)
- Update success toast message so that the user is informed if rules
were skipped.
