Reviewed by Rob Buis.

A new API was added to BlackBerry::Platform::Graphics for destroying
thread-specific data generated on the compositing thread when we blit
buffers. The buffers are otherwise created and destroyed on the WebKit
thread, which doesn't give platform any opportunity to destroy the
thread-specific data.

This patch adds calls to the new API to avoid leaking resources.
