Describe the feature

There is currently no documented examples or tests of reserved capacity CodeBuild projects.

Use Case

I discovered this issue while attempting to add the aws/codebuild/windows-base:2019-3 image to WindowsBuildImage, see #29616 (comment) for additional context

Proposed Solution

Adding a fleet prop to the Project construct shouldn't be too much work, and will allow us to easily check that the fleet property is present when a WindowsImageType.SERVER_2022 image is given
