Performance optimizations

• Intel Processor Graphics and Xe architecture-based Graphics:
  • Improved performance of Winograd convolution.
• Intel Architecture processors
  • Introduced initial performance optimizations for future Intel Core processor with Intel AVX2 and Intel DL Boost instructions support (code name Alder Lake).
  • Improved performance of int8 primitive for processors with Intel SSE4.1 instruction set support.
  • Improved performance of int8 and bfloat16 RNN and Inner Product primitives.
• AArch64-based processors
  • Improved performance of Winograd convolution with ArmCL
  • Improved performance of int8 convolution with ArmCL
  • Added JIT support for Aarch64 and JIT reorder implementation

New Functionality

• Introduced int8 support for LSTM primitive with projection for CPU.
