This reverts commit a86ef94656.
The converters are still in a separate target that must be included manually. This allows targets that depend on FML but not Dart runtime not have to depend on the runtime.
Adds a test that includes this target and tests image decompression from assets. There is also a test for the standalone DartConvertor in shell_unittests but not in fml_unittests be cause FML uni-tests cannot yet launch a VM. I will work on adding fixtures for those.
If the image is a cross-context image that might be read from the GPU thread
during onscreen rendering, then it is not safe to read it concurrently from
the IO thread as part of Image.toByteData.
If the GPU thread does not have a graphics context, then fall back to
converting the image on the IO thread.

This ensures we rasterize into the canvas passed in as subclasses may reimplement AcquireFrame in different ways that don't utilize the canvas object passed in (such as Fuchsia's flutter_runner::CompositorContext).
This is a duplicate of flutter/engine#13360 with the test switched to use the software backend instead of the GL backend.
After some debugging and testing on another GL embedder I think the issue with the test is some bug having to do with the GL implementation in the test harness specifically.
