onscreen: Make the resize callback work the same as the frame callback

Browse Source 
When adding the frame callback API in 70040166 we decided on a common
idiom for adding callbacks which would return an opaque pointer
representing the closure for the callback. This pointer can then be
used to later remove the callback. The closure can also contain an
optional callback to invoke when the user data parameter is destroyed.
The resize callback didn't work this way and instead had an integer
handle to identify the closure. This patch changes it to work the same
way as the frame callback.
