Lioncash 4f2b60c8e7 dynarmic_tests: Remove skyeye interpreter
This is quite a messy interpreter and would require a large amount of
work to bring it up to speed to begin implementing newer portions of the
AArch32 instruction set into Dynarmic.

Given we already have fuzzing with Unicorn set up for
AArch64/AArch32, we can get rid of this and unify our testing
infrastructure.

This will also make building the tests much faster, given a whole
interpreter doesn't need to be built anymore as part of the project.
