Subject: [PATCH] [XboxKrnl/xconfig.cc] - Stub ExSetXConfigSetting and
 ExReadModifyWriteXConfigSettingUlong

- Stubbing ExSetXConfigSetting and ExReadModifyWriteXConfigSettingUlong
- ExSetXConfigSetting is a simple value swap from buffer_ptr
- ExReadModifyWriteXConfigSettingUlong handles combined values with buffer_ptr holding the replacement values
- added log to show what the new setting should be and what is being replaced
- To Implement would need to convert settings to strucs
