codebuild : macOS 15 base image support

[ayush-panta]

Describe the feature

Although CodeBuild supports the macOS base:15 image (ref), the CDK does not support this.

Use Case

I want to be able to set the version of runners to macOS 15 through the CDK.

Proposed Solution

I added an option for the BASE_15 image. This simply involved copying the logic for BASE_14 and changing 14 to 15. This can be seen in my PR.

Hi @ayush-panta,

Thank you for submitting this feature request and the accompanying PR #35836!

The analysis indicates this is a straightforward addition following the existing pattern. AWS CodeBuild does support the macos-arm-base:15 image, and adding it to the CDK library would simply involve adding a new constant to the MacBuildImage class, similar to how BASE_14 is defined.

This is a nice addition that would allow CDK users to leverage the latest macOS 15 runners. The CDK team will review your PR and provide feedback. Thank you for your contribution to the AWS CDK!

Hi @pahud,

Thank you for your response!

May I ask, how long should I expect the review process for this to take? I created the PR a few weeks ago but only created the issue yesterday, so that may have made this take longer than I expected.
