EPR #394700 - SubAllocation Scheme for ConstantBuffers Implemented in GLL.
This CL introduces sub-allocation for constant buffer for all Asics and currently supported by GLL, it can easily be opted in by OpenCL, OES as well.
OpenCL changes for Sub-allocation scheme for constantbuffers. For more info please see CL#1172125

EPR #420701 - WDDM 2.0
- Indicate lite initialization via a new parameter initLite. This is needed as OCL\OGL can query devices first and lot of setup in IOL may not be really needed. On Win10, we create paging\fences for sync which dont get destroyed by the OS unless process is killed. This may prevent slave GPU powerdown in PX cases.
- Disable WriteFence for OpenCL for now.

ECR #399840 - OpenCL Runtime HW Debug support development
- use device to control debugger registration and exception notification so that debug event will not be tied to any particular queue.
- use aqlCodeInfo parameter for clHwDbgMapKernelCodeAMD() to be consistent with clHwDbgGetAqlPacketInfoAMD()

ECR #304775 - Add batching to the device enqueue for possible asynchronous execution
- Increase the max device queue size to 512KB. That will allow to pass conformance tests that enqueue more jobs than the queue size.

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
- 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.
