refactor(core): Reorganize error hierarchy in core and workflow packages (no-changelog) (#7820)

Ensure all errors in `core` and `workflow` inherit from
`ApplicationError` so that we start normalizing all the errors we report
to Sentry

Follow-up to:
https://github.com/n8n-io/n8n/pull/7757#discussion_r1404338844

### `core` package

`ApplicationError`
- `FileSystemError` (abstract)
	- `FileNotFoundError`
	- `DisallowedFilepathError`
- `BinaryDataError` (abstract)
	- `InvalidModeError`
	- `InvalidManagerError`
- `InvalidExecutionMetadataError`

### `workflow` package

`ApplicationError`
- `ExecutionBaseError` (abstract)
	- `WorkflowActivationError`
		- `WorkflowDeactivationError`
		- `WebhookTakenError`
	- `WorkflowOperationError`
		- `SubworkflowOperationError`
			- `CliWorkflowOperationError`
	- `ExpressionError`
		- `ExpressionExtensionError`
	- `NodeError` (abstract)
		- `NodeOperationError`
		- `NodeApiError`
	- `NodeSSLError`

Up next:
- Reorganize errors in `cli`
- Flatten the hierarchy in `workflow` (do we really need
`ExecutionBaseError`?)
- Remove `ExecutionError` type
- Stop throwing plain `Error`s
- Replace `severity` with `level`
- Add node and credential types as `tags`
- Add workflow IDs and execution IDs as `extras`
