[feature, perf] add alogrithm to chain command buffers in container

Browse Source 
This feature is part of performance improvement to dispatch and start
command buffers as primary batch buffers.
When exhausted command buffer is closed, then reserve exact space for chained
batch buffer start and bind it to the next command buffer.
When closing command buffer, then save ending pointer and
reserve aligned space.
