[aws-timestream] High level components for Database and Table

With Timestream entering GA now is the perfect time to add high level CDK components for the core components of the service - the database and table constructs.

### Use Case

Currently Timestream is only available using the CloudFormation default constructs, part of the CDK philosophy is to build upon these basic constructs to make simpler, intuitive constructs that can be used in more complicated patterns.

### Proposed Solution

Building constructs for Timestream database and table.

This is a :rocket: Feature Request

Start by reviewing the existing CloudFormation default constructs for Timestream and the CDK patterns for higher-level service constructs. The work is complete when high-level constructs for a Timestream database and table are available and cover the core components described in the request.
