Fixes #18694, #8712 This change adds an option to suppress indentation in CloudFormation template files. Suppressing indentation will reduce the file size of templates. Indentation can be set by enabling for specific Stacks using the new `suppressTemplateIndentation` property in `StackProps`, or globally using the new `@aws-cdk/core:suppressTemplateIndentation` context key. This PR provides additional template size reduction beyond the indentation change in #19656. @rix0rrr @mackalex @PatMyron ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license*
