fix(cdk/schematics): account for new karma builder (#30907)

angular/angular-cli#29640 introduced a new Karma builder that appears to be the default in v20. These changes update our code so that the new builder is recognized.

I also move the names of the builders out into a constant so they're easier to update.

(cherry picked from commit 22876a9)
