Jim Graham 80d757ef56 Change default TileMode for blur ImageFilter objects to null (flutter/engine#55552) ...

Fixes https://github.com/flutter/flutter/issues/154935

Historically ImageFilter.blur supported setting a TileMode and had a default mode of `clamp`, but few developers actually set the value and the default was not appropriate for some common uses like as a backdrop filter where the clamp mode produces flashing when scrolling high frequency pixel content underneath a blurred title bar.

This PR removes the default tile mode instead allowing a null value as the default which will allow the engine to use an appropriate context-dependent default tile mode depending on the action being performed. Typically:

- decal for rendering operations and saveLayers and ImageFilterLayer
- clamp for image operations
- mirror for backdrop filters
