This commit extends the refactoring done in #14549 to handle host-thrown exceptions in addition to guest-thrown exceptions. Effectively here the host entrypoints are now annotated with how to handle
ThrownExceptionin addition to entrypoints to ensure that host-thrown exceptions are considered traps as opposed to being caught by wasm.Closes #14577
