[LV2] [PATCH] Make ui:resize a lv2:ExtensionData, too.

[Hanspeter Portner]

ui:resize can be used bidirectionally:
* plugin can use ui:resize as host feature to request the parent window
to resize
* host can use ui:resize extension data to request the plugin window to
resize

There are plugins that define:
* lv2:extensionData ui:idleInterface, ui:resize .

According to the documentation this makes only sense, but this does not
pass sord_validation, as ui:resize is ONLY defined as a lv2:Feature.

Plugins should be able to request/signal either support to the host:
* lv2:requiredFeature ui:idleInterface, ui:show ;
* lv2:extensionData ui:idleInterface, ui:show ;
