#6049: fix page state namespace labels; support custom labels for enums

[twschiller]

What does this PR do?

• Closes Update naming in UI for Page State #6049
• Add support to Schema Field for using oneOf + const to provide options with choices (see discussion)
• Updates labels for Page State locations in the Get/Set Page State Bricks. The values are kept the same for backward compatibility
  • extension → Private
  • blueprint → Mod
  • shared → Public
• Adds analysis rules for improper usage of Page State Location
• Update Page State labels in the Data Panel
• Adds a isPageStateAware method to bricks to determine if the bricks may read/write page state. That's used to determine whether the panel is shown in the Data Panel

Discussion

• RJSF supports a non-standard enumNames property, but it's semi-deprecated. JSON Schema is also likely in the future going to drop support for non-standard field. Therefore, I went with the oneOf + const approach, which is also what we use in the Form Builder.
