[dynarmic] simplify assert macro usage (Only ASSERT/DEBUG_ASSERT are needed) (#2890)

- replace instances of ASSERT() with those where UNREACHABLE() should be used instead
- debuggers exist for a reason, you can't just debug an issue in dynarmic with just printing fancy text... you need to inspect values and alldat - while yes the asserts are "useful"; there is this beautiful thing called backtraces
- this will indirectly speedup the main decoder loop because of the added UNREACHABLE()
- this also removes a bunch of macros that were redundant
- the weird trick of [&](){}() is really funky, just do what everyone has done for the past 30 years and use a `do { <thing> } while(0)` :)

I may or may not have missed one assert or messed up my regex substitutions...
