[Feature]: when set "stylelint.configFile",merge the config in .stylelintrc in the project and the config in "stylelint.configFile"

[Whisper]

What problem does this feature solve?

I have a global stylelint config, so i set "stylelint.configFile"
But I have specific rules in some projects, so I need create a .stylelintrc.json in the project to set the specific rules
and I need the rules which set in "stylelint.configFile" needn't set in project again
so merge them like eslint is a good way

How does this feature solve the problem?

if there is a .stylelintrc.json in the project folder, merge them
and the file in project root has higher priority

What are some alternatives to this feature?
