API groupings should be alphabetized

[jverkoey]

Consider the following recent output:

## MDMSchedulerActivityStateIdle
## MDMSchedulerActivityState
## MDMSchedulerDelegate
## MDMConsoleLoggingTracer
## MDMRuntimeFeatures
## MDMPerforming
## MDMComposablePerforming
## MDMTransaction
## MDMScheduler
## MDMTransactionEmitting
## MDMTracing
## MDMRuntimeActivityState
## MDMRuntimeDelegate
## MDMSchedulerActivityStateActive
## MDMRuntime

These groups should be alphabetized.
