Tweak the primary flutter build rule so that fuchsia is more similar to
other platforms in how tests and the shell are built.

Only embedder_unittests and GLFW tests are disabled on Fuchsia now.

TEST: Ran unittests on host/fuchsia; workstation on fuchsia
BUG: fxb/53847, fxb/54056

Moved to RMSE for image comparison to account for slight variations in golden image production.  (also fixed a flakey test)

This is required by some Vulkan 1.0 drivers. For example,
MoltenVK through goldfish ICD when running in the emulator.

It looks like half the code in this function was updated to use the
main bundle but this one line was still only using the _dartBundle. I am
pretty sure that is a mistake and instead we want to use the mainBundle
as a backup both to find the plist and to find the assets.
