Refactor the setting to make unit test easier (#22405)

Some bugs caused by less unit tests in fundamental packages. This PR refactor `setting` package so that create a unit test will be easier than before. - All `LoadFromXXX` files has been splited as two functions, one is `InitProviderFromXXX` and `LoadCommonSettings`. The first functions will only include the code to create or new a ini file. The second function will load common settings. - It also renames all functions in setting from `newXXXService` to `loadXXXSetting` or `loadXXXFrom` to make the function name less confusing. - Move `XORMLog` to `SQLLog` because it's a better name for that. Maybe we should finally move these `loadXXXSetting` into the `XXXInit` function? Any idea? --------- Co-authored-by: 6543 <6543@obermui.de> Co-authored-by: delvh <dev.lh@web.de>
