fix(core): incorrectly validating properties on ng-content and ng-container (#37773)

Fixes the following issues related to how we validate properties during JIT:
- The invalid property warning was printing `null` as the node name
for `ng-content`. The problem is that when generating a template from
 `ng-content` we weren't capturing the node name.
- We weren't running property validation on `ng-container` at all.
This used to be supported on ViewEngine and seems like an oversight.

In the process of making these changes, I found and cleaned up a
few places where we were passing in `LView` unnecessarily.
