[MERGE #3506 @Cellule] Default case in InliningDecider::GetBuiltInInfoCommon

Merge pull request #3506 from Cellule:cleanup

When turned off `ENABLE_SIMDJS` it changed the behavior of the switch case in `InliningDecider::GetBuiltInInfoCommon`
Turns out we only use the return value for -off:<some inlining feature>, so this is just a clean up change
