feat(codebuild): attribute-based compute type for Fleet (#32251)

### Issue # (if applicable)

None

### Reason for this change

AWS Codebuild supports for creating Fleet with attribute based compute type.
https://docs.aws.amazon.com/codebuild/latest/userguide/fleets.html#fleets.attribute-compute

You can specify minimum vCPU, disk and memory sizes. Codebuild automatically selects the instance type based on the compute configuration.

### Description of changes

Add `computeConfiguraion` prop to `FleetProps`.

### Description of how you validated changes

Add both unit and integ tests.
