Editor: Fix console warnings

[obenland]

Fixes warnings like:

Bottom margin styles for wp.components.RangeControl is deprecated since version 6.7 and will be removed in version 7.0. Note: Set the `__nextHasNoMarginBottom` prop to true to start opting into the new styles, which will become the default in a future version.

36px default size for wp.components.RangeControl is deprecated since version 6.8 and will be removed in version 7.1. Note: Set the `__next40pxDefaultSize` prop to true to start opting into the new default size, which will become the default in a future version.

Proposed changes:

• Sets __next* props on editor controls for forwards compatibility.
• Adds block-editor-block-inspector class on PluginDocumentSettingPanel to define margins between controls.

• The __next40pxDefaultSize and __nextHasNoMarginBottom props are applied to TextControl, yet the commit message and deprecation warnings reference RangeControl. Please verify if these props are intentionally applied to TextControl or if they should be limited to RangeControl only.
