@aws-cdk/toolkit-lib: include NodejsFunction esbuild logs in ioHost notifications

[dreamorosi]

Describe the feature

When working with the new @aws-cdk/toolkit-lib and implementing a custom ioHost I'd like to have all the logs emitted by CDK included in the notifiy callback.

Right now this is not the case, and some logs like the one emitted by the esbuild bundling process are not included.

Use Case

When using the new toolkit customers can control all the notifications and apply complex filtering/workflows on them. Right now the logs emitted by the bundling are excluded from these notifications and end up directly to stdout.

Proposed Solution
