Typed[Object]Plug : Move .inl to Implementation.h

We use `.inl` files to store inline implementation that we want the compiler to see, but which we don't want to clutter up the header with, so the headers are more human-readable. These files don't match that pattern - they're to be included in a single `.cpp` file and used to explicitly instantiate the template.

   - The `display` and `view` default values are now interpreted as the default defined by the current OpenColorIO config, rather than as invalid values. This means that a node without `display` or `view` specified is no longer a pass-through as it was before.
 - gaffer test : Replaced `-performanceOnly` flag with `-category` argument which may be set to `performance` for the same as the old `-performanceOnly`, or `standard` for the converse.
 - VisibleSet : Renamed `VisibleSet::match()` to `visibility()` and changed return type.
+- TypedPlug : Moved implementation code from `TypedPlug.inl` to `TypedPlugImplementation.h`.
+- TypedObjectPlug : Moved implementation code from `TypedObjectPlug.inl` to `TypedObjectPlugImplementation.h`.
