RELAND of this commit. Had to fix fuzzer build errors. Optimize performance of SecondaryCommandBuffers and enable them as the default build option. To disable this set angle_enable_custom_vulkan_cmd_buffers=false in your build args. This CL enhances the PoolAllocator to have a "fast" mode that can be enabled at class creation. This mode uses an alignment of 1 byte and enables a fastAllocation() call that avoids some bookkeeping overhead. The SecondaryCommandBuffer uses this fastAllocation() function. Furthermore the fast path of fast allocate, using the current page, is inlined for maximum speed. Jamie Madill also updated the SecondaryCommandBuffers to pre-allocate blocks so that the commands occur linearly in memory. This speeds up processing with improved cache coherency and minimizes overhead when recording commands. Also the core Draw functions and their state updates are all inlined as well as the common functions to initialize commands and to copy command pointer data. This change also includes some new, custom commands. One is imageBarrier that is a specialized version of pipelineBarrier that only performs a single image layout transition. There are customized versions of various Draw commands to minimize copying of parameters. There are also specialized commands to bind[Graphics|Compute]Pipeline that have the pipeline type built in to the command. More custom commands and command data size optimizations will be made in follow-on commits.
