FIRE-35083 - Floater_stats.xml has incorrect stat_view setting for materials

Issue was caused by the stat_bar 'nummaterials' setting being used for the stat_view 'material' setting which was looking for a BOOL and was given a S32.

Only the debug release would throw a bug splat. Release would give a warning and return false.

Changes Include:
Modified setting.xml
- Added new Boolean OpenDebugStatMaterials to the settings.xml to match the naming of the other Statistics expand/collapse display settings.
Modified floater_stat.xml
- Updated the setting on the stat_bar 'nummaterials' to use the DebugStatModeMaterials setting.
- Updated the setting on the stat_view 'material' to use the OpenDebugStatMaterials setting.
