feat(codebuild): add new environment types

[awszhen]

Issue # (if applicable)

Closes #32728.

Reason for this change

Recently, CodeBuild released a new set of environment types which can be found here: LINUX_EC2, ARM_EC2 and WINDOWS_EC2. The CDK needs to be extended to support these new environment types.

Description of changes

Added LINUX_EC2, ARM_EC2 and WINDOWS_EC2 values to EnvironmentType.

Description of how you validated changes

Tests has been added. I ensured that the CDK was able to build, and that the output CloudFormation stack had the correct resources.
