DefaultPropsProvider doesn't work with @mui/x packages

[trungutt]

Steps to reproduce

Following the migration guide to PigmentCSS, we use DefaultPropsProvider to migrate all our defaultProps customizations.

These customizations don't appear to work with PigmentCSS. Note that customizations from normal MUI components (Stack/Box/Typography...) continue to work.

One simplest example is to have this is to customize the DatePicker's opening icon

and under PigmentCSS build, it always shows the default opening icon and not the custom one.

Note

We use a simple function to iterate through all MUI components and extract out all defaultProps to put in DefaultPropsProvider.

Expected behavior

MUI X packages should work with DefaultPropsProvider like any other normal MUI components.
