[WebAssembly] Fix: fixCallUnwindMismatches after fixCatchUnwindMismatches (#187484) `fixCallUnwindMismatches()` adds an extra try block around call sites with incorrect unwind targets. `fixCatchUnwindMismatches()` handles catch blocks that have incorrect next unwind destinations. Previously we ran `fixCallUnwindMismatches()` first and then ran `fixCatchUnwindMismatches()`. The problem is that `fixCatchUnwindMismatches()` wraps entire try blocks which can change the unwind destination of the calls inside. If the calls had an incorrect unwind target to begin with, they will be wrapped already and so the outer wrapping won't alter their unwind target. However, if they start out with a correct unwind target, they won't get wrapped and then that can be messed up by `fixCatchUnwindMismatches()`. The fix is to run `fixCatchUnwindMismatches()` first. `fixCallUnwindMismatches()` never messes up the result of `fixCatchUnwindMismatches()` so this is the correct order. Resolves #187302
