This is the accompanying change for https://github.com/flutter/engine/pull/8148 and it needs the engine PR to land first.

* No shrinking for BackdropFilter's cull rect

This will be a breaking change. Our old behavior may generate confusions
for a sample app like our added golden test: Skia will shrink the cull
rect (and thus the filtered area) to the text. The new behavior will
fill the BackdropFilter to its parent/ancestor clip. This is more
in align with our clip behaviors (no clip by default).

If this breaks your app, wrap the BackdropFilter with a ClipRect.

[wip] The golden images are not uploaded yet. I'll wait for the initial
round of review to approve the golden test before uploading them.

* Statically define the callback

* Add TODO to remind the hacking code removal

* Nit fix

* Update goldens

This will handle paths with symlinks that resolve to the same location.

* Always composite PhysicalModels
* Update tests to check layer tree instead of canvas for Physical shadows

* No image shader caching in default shader warm-up

It turns out that no matter how small the image is, too much memory will
be used. Hence remove the image shader caching and let the client
implement itself based on needs.

Fixes https://github.com/flutter/flutter/issues/29172

* Fix

* Install JDK and Android SDK only for integration and build tests
