gst/pad: [Ghost]PadBuilder: inherit name from template or target when possible
This commit adds convenience auto naming in the following cases: * When building from a non wildcard-named template, the name of the template is automatically assigned to the Pad. User can override with a specific name by calling `name()` on the `PadBuilder`. * When building with a target and no name was provided via the above, the GhostPad is named after the target.
