ol.layer.Layer not included in full build ol.js

[csozoli]

The ol.layer.Layer class would need an @api annotation, otherwise it is not visible in full ol.js build.
The case where this is needed is e.g. layer tree traversal to distinguish “leaf” layer from group layer.
An example of failure can be seen here: https://jsfiddle.net/tpcxL1e9/
Tested with v5.3.0.
