[CI] Use clang-format from nightly builds (#5126)

[Contributing guide](https://github.com/intel/llvm/blob/sycl/CONTRIBUTING.md) suggests using the same version of clang-format, that is build from tip of this repository. That caused problems in the past, where the newer clang-format does the job differently to what's being used in CI. This patch switches to default clang-format installation to the one, that comes with nightly builds. This would allow us to minimize the impact of different clang-format versions.

[CI] Add container users to video group (#5101)

Accessing `/dev/dri` device (GPU) requires user to be in `video` group. Change containers to include `sycl` user into the group.

Also change workflow to build containers in pre-commit without pushing to the registry to make sure containers are still buildable.

[SYCL] Switch to using blocking USM free for OpenCL GPU (#4928)

Whenever a kernel is enqueued on GPU, the GPU driver records the state
of all USM pointers that might be used in an indirect fashion. Because
of this, these pointers cannot be freed until the execution of the kernel
is finished.
This change addresses this problem for OpenCL by using a blocking version
of free, while Level Zero already handles this by deferring USM release.
The change is temporarily limited to OpenCL GPU until a bug in OpenCL CPU
runtime is resolved.

[SYCL][NFC] Fix special member functions for GCC 11.2 and C++20 (#5068)

I got an issue while compiling the SYCL runtime on Ubuntu 21.10 G++ 11.2 and C++20.
Please add more modern configurations to your GitHub Actions to test at least with the latest compilers and latest languages.
While SYCL 2020 requires at least a C++17 compiler, it should not break with C++20 or C++2b.
