block: Convert 'block_resize' to coroutine
block_resize performs some I/O that could potentially take quite some time, so use it as an example for the new 'coroutine': true annotation in the QAPI schema. bdrv_truncate() requires that we're already in the right AioContext for the BlockDriverState if called in coroutine context. So instead of just taking the AioContext lock, move the QMP handler coroutine to the context. Call blk_unref() only after switching back because blk_unref() may only be called in the main thread.
