fix(ivy): ngcc - render decorators in UMD and CommonJS bundles correctly (#31614)

In #31426 a fix was implemented to render namespaced decorator imports
correctly, however it turns out that the fix only worked when decorator
information was extracted from static properties, not when using
`__decorate` calls.

This commit fixes the issue by creating the decorator metadata with the
full decorator expression, instead of only its name.

Closes #31394
