Fix StyleBox ignoring region rect and ProgressBar using center size
ProgressBar used the center size of the stylebox to calculate its minimum size, thus disallowing certain setups.
If the old behaviour is wanted, it can be forced by providing a custom minimum size, or by giving proper margins to the stylebox.

Fixes #17779.
