Added "RemovePassTemplate" method. (#5039)

Browse Source 
* Added "RemovePassTemplate" method.

Signed-off-by: garrieta <garrieta@amazon.com>

* RemovePassTemplate only allows to remove PassTemplates
created with the Runtime API. It now asserts if there are Passes
referencing the PassTemplate that should be removed.
