ECR #304775 - Optimization for rectangular copies(Part2). Due to HW restriction of 14bits for src and dst pitch, its advantageous to choose optimal bpp. Higher the bpp the larger the byte pitch. This indirectly helps to reduce the number of packets for buffer copy(line by line vs a single sub_win raw packet)

ECR #304775 - Device enqueuing
- Provide scratch buffer offset for generic address space
- Use single scratch buffer for all available queues. Each queue will have a unique subbuffer in the global buffer

ECR #304775 - Device enqueuing
- Add L2 cache flush after the scheduler execution. Although CP has to work with L2 cache, it seems some functionality relies on direct memory access and without explicit L2 flush CP can pick old values in the template.
