fix: Fallback to full reload if React version doesn't support Fast Refresh

[n3tr]

fix #9807

Changes

Fallback to the full reload if React version doesn't support Fast Refresh

• Overwrite FAST_REFRESH to false if the current react version doesn't support (< 16.9.0)
• Remove Fast Refresh warning on the older react version since we will automatically fallback to do full reload.
• Change the minimum supported version to 16.9.0 per react-refresh-webpack-plugin's prerequisites.
