I2021 (uxlfoundation#154)

* initial sycl support

* adding missing __init__

* adding sycl_buffer code

* sycl_buffer code compiles, still crashes though

* fixes

* setting default context

* allowing daal result tables to stay on GPU without any copy

* removed deprecated examples, fixed version check

* examples and tests for Covariance, KMeans, PCA, LogReg

* changes of conda-build

* switching back to default CPU context

* streaming examples for covariance and moments of low order

* processing the exception when device is unavailable

* batch examples for linear regression and moments of low order

* clang-format before generating

* custom build with/without dpcpp

* brute force KNN with GPU

* GBT regression with GPU example

* build with the release version of dpcpp

* Update build.sh

* add clang-tools for clang-format

* conditional dpcpp libs

* sycl examples are mooved to subpath

* enable boosting algorithms in 2020.0 version

* fix lin/win EOL

* fix lin/win EOL

* gbt cls 2020.0 features in example

* outdated assertions in tests

* relative paths in sycl examples

* fix streaming examples with stream.py

* PCA transform with sycl example
