host compiled custom-clang-tidy

Is your feature request related to a problem? Please describe.

• it's very slow
• can't run its test on local computer unless compiling entire llvm from source

Describe the solution you'd like

• create a workflow with workflow_dispath (manual runs only) / every time a week
• make it create artifact of clang-tidy with plugins
• download and add the binary manually (or curl from other build scripts?)
• use pre-generated clang-tidy binary to use in local development environment and speed up workfow

Describe alternatives you've considered

should probably just update clang-tidy plugin to latest LLVM so we don't have to download legacy LLVM 12 and finally merge #2341
