Changing material component property inspector to dockable view pane

• Inspector is locked to a specific entity and material assignment ID
• All modifications are made via the material component request bus
• Removed complicated configuration management in editor material component
• Multiple material property inspectors can be opened
• Multiple materials across different entities can be edited simultaneously
• No longer blocks the viewport or other interactions
• Added functions to material component request bus for retrieving material slot labels, default materials, getting and setting property and UV overrides
• Added more asset related types to material property value conversion from any
• Added support for static heading widget on top of atom tools inspector, currently used for menus and messages
