Jim Graham ab7af6ffb2 Honor blur tile mode in BackdropFilter widget on Skia backend (flutter/engine#55640) ...

The blur ImageFilter has a tile mode that describes how to sample pixels near the edge of the source. When used as a BackdropFilter this behavior is important as the wrong tile mode can cause distracting flashing as app content is scrolled under foreground widgets that blur their background. Unfortunately the Skia backend used to default the tile mode for all backdrop filters to `clamp` mode with no way to update it and that mode was the one that produced the most distracting flashing.

Recently Skia opened up control over the tile mode used for backdrop filters and we now take advantage of that capability so that app developers can now set the tile mode to a nicer value.
