Antares

New updates:

1. **Change of Auto-scheduling**: Enhanced CPU(c-scpu/c-mcpu/c-mcpu_avx512) & IPU(renamed from c-gc to c-ipu) auto tuning search space.
2. **Change of JIT Tuning**: Pytorch/Tensorflow JIT Plugin is changed into *local tuning* by setting `ANTARES_ROOT`. (Tuning over rest-server is canceled)
3. **Change of Installation**: Allow non-root users to install Antares components.
4. Many other fixes.

New features:
1) Supporting More Backends: e.g. SYCL for CPU, ROCm for Windows, OCL for Android, etc.
2) Enhanced Tuning Mechanism OpEvo-2: Faster and Effective Tuner than Legacy Ansor.
3) AB Backend interface for all hardware (e.g. ab::init, ab::launchKernel, ..)
4) Enhanced Antares HLSL library using DXC-6.0, tuning efficiency is much improved.
5) Initial support for inter-op tuning (only for small graph in this version, large graph tuning will be supported in the following releases).

This version is frozen to keep legacy usage of Antares (intra-op optimizations, v0.1 api for directx12).
