registerBridgeTypeLazy method
Lazy variant of registerBridgeType: registers a deferred thunk under
nativeType in the type-only lookup without building the BridgedClass
until the type is first resolved by toBridgedInstance.
Used by the warm-parent / baseline registration so importing a bridge package registers the type baseline without forcing every one of the package's classes to build up front (import-optimization plan step #17).
Implementation
void registerBridgeTypeLazy(Type nativeType, BridgedClass Function() thunk) {
_bridgedClassesLookupByTypeOrNew.putThunk(nativeType, thunk);
_invalidateResolutionCache();
}
