Run codecov on all engines

[axic]

@chfast can you have a look why codecov is failing?

To be clear, why compilation fails:

FAILED: CMakeFiles/wabt.dir/src/string-view.cc.o

The compiler went OOM.

@chfast would it be a lot of work splitting up coverage into:

• running all engines (this will not allow us to see if the eei is covered properly)
• running only wabt to see if it covers the entire eei properly

A bit. On codecov you can tag different data uploads, but codecov is not able to filter these in web UI. Maybe coveralls can do it.

@chfast thanks for fixing this!
