(cloudwatch): allow period override on LogQueryWidget

### Describe the feature

Allow overriding the default period on a LogQueryWidget.

This is possible on `GraphWidget` but not on `LogQueryWidget`. (there are in fact quite a few props other that don't exist on `LogQueryWidget`).

### Use Case

I want to run a Logs Insights query over a large time period, ignoring whatever the global setting is in the dashboard.

### Proposed Solution

Extend `LogQueryWidget` with those of `GraphWidget`.

### Other Information

_No response_

### Acknowledgements

- [ ] I may be able to implement this feature request
- [ ] This feature might incur a breaking change

### CDK version used

2.166.0

### Environment details (OS name and version, etc.)

MacOS

Start by locating the TypeScript definitions and tests for LogQueryWidget and GraphWidget in the AWS CDK CloudWatch module. Compare the widget properties, identify the period handling and its test coverage, then verify that a LogQueryWidget can override the dashboard's global period without changing existing behavior.
