Computes the max intrinsic width of a configured TextPainter.

This is a convenience method that creates a text painter with the supplied parameters, lays it out with the supplied minWidth and maxWidth, and returns its TextPainter.maxIntrinsicWidth making sure to dispose the underlying resources. Doing this operation is expensive and should be avoided whenever it is possible to preserve the TextPainter to paint the text or get other information about it.
