This should make things a bit easier to read and edit and plays nicer with LSP.* A bunch of GC op filtering that was logically part of fixing up an instruction is now actually part of `GcOp::fixup`. Also a redundant `op.fixup()` call was removed, `GcOp::fixup` takes `&self` instead of `&mut self` since it returns a new `GcOp` now instead of mutatint `self` in place, etc...* A few other small things here and there.* Fix `GcOps` fuzz mutator testsAlso remove the `test_wat_string` test because it isn't really helpful at thispoint, it is just something we have to remember to update whenever weadd/remove/change `GcOp`s while not giving us anything in return.
