Brandon DeRosier 07803f501e [Impeller] Aiks image filters; allow setting effect transforms after FilterContents instantiation. (flutter/engine#45530) ...

These are API improvements on the way to solving
https://github.com/flutter/flutter/issues/131182.

* Remove `effect_transform` and `is_subpass` from the static
`FilterContents` factories. These are for internal use only.
* Replace `impeller::Paint` filter procs with Aiks `ImageFilter`
factories similar to `ColorFilter`. This gives Aiks a simple interface
for constructing filters and prevents possible state cloning bugs when
copying filters into `EntityPass`.
* Allow for setting filter inputs, setting the effect transform, and
enabling subpass mode on a filter chain after it has been instantiated.
This will allow us to sample coverage in `EntityPass` without rendering
any snapshots using rect filter inputs.
