[ci] feat: add GitHub actions workflows for building/testing/docs (#2)

* disable windows runner for now (chocolatey jack package is broken)
* install jack and pcre from homebrew for macOS workflow
* install libjack-jackd2-dev libpcre3-dev for linux workflow
* add additional libjack location candidate for macOS / homebrew
* make library name patterns const strings
