UX Workflow improvements for Physics Materials (#1237)

- Added button to PhysX Collider Component in PhysX Mesh's field to open FBX Settings.
- Added button Material Selection to open the physics material library in Asset Editor.
- Default Material in PhysX configuration is read only and consistent with the text in combo boxes.
- Material configuration field "Surface Type" renamed to "Name"
- Fixed bug in EditorColliderComponent where the material selection was not updated when changing the library.
- Fixed bug where the materials selection was not set to default when a physics material from the asset was not found in the library.
- Added attributes 'BrowseButtonEnabled' and 'BrowseButtonVisible' to PropertyAssetCtrl.
- Updated physx configuration setreg files of AutomatedTesting project.
