SWDEV-124171 - adding support for p2p OCL in rocm stack
	- Add cl_amd_copy_buffer_p2p extension for P2P transfers. The extension adds a new API entry - clEnqueueCopyBufferP2PAMD() which allows to transfer CL buffers between different CL contexts on different GPUs. If P2P isn't possible, then double copy performed
	- Also the app can query the P2P support capabilities for the device. A list of P2P accessible devices can be returned for the current device
