Docker support for 1:1 environment CI vs local

[neatudarius]

Docker file for 1:1 environment CI vs local. Note: Docker environment will be optional. We will still be able to run directly on local host machine, but we need a determinist setup to test with the same env that we on CI (for special cases - check clang 18 failure in #29 ).

• Create Docker file which is identical to image that we exactly use on CI (e.g. , pull ubuntu-24.04 from Git Actions, run our scripts to install toolchains).
• Add scripts to avoid duplication of comamnds in CI YMLs vs local flows.

The Makefile has most of the build scripting already.

We may want to explore using docker layers for the different LLVM versions. However, I'm pretty sure the full matrix might then consume all the disk on the SSD on my work laptop.

However, installing multiple compilers can leave some libraries shared between them.
