What this PR does / why we need it:

To reduce the number of changes in https://github.com/Azure/azure-service-operator/pull/2084, we want to pull naming changes forward, allowing more meaningful review.

This PR changes our standard suffix from _Status to _STATUS and updates all affected code.

Prerequisites

• [ ] Merge PR #2444 (will require a rebase of this PR)

Special notes for your reviewer:

• Type sorting for file generation is now case insensitive (so that the change from _Status to _STATUS doesn't reorder types)
• Double underscores (__) in file names now won't happen
• While StatusARM has a word break, STATUSARM does not, so we explicitly force filenames to split into status_arm to maintain naming conventions
