[DEV-9278] US maps with states, state text labels missing

[khartco]

[DEV-9278]

State labels enabled by default, add stroke color around state labels for increased contrast. Tooltips to recommend state labels be enabled.

Testing Steps

• Create a new US map, or use a config without the displayStateLabels specifed.
  • State labels should be enabled by default
• Use a US map config with colored state background colors
  • On light colored states: State labels should appear dark gray with a white stroke
  • On dark colored states: State labels should appear white with a gray stroke
• In the editor, the toggle for state labels should have a new tooltip recommending to leave enabled.

Self Review

• I have added testing steps for reviewers
• I have commented my code, particularly in hard-to-understand areas
• My changes generate no new warnings
• New and existing unit tests are passing
