fix(ivy): support module.id as @NgModule's "id" field value (#30040) 

Prior to this commit, the check that verifies correct "id" field type was too strict and didn't allow `module.id` as @NgModule's "id" field value. This change adds a special handling for `module.id` and uses it as id of @NgModule if specified.
