Pre-eliminary support for LLVM releases and resolc binary releases by streamlining the build process for all supported hosts platforms. - Introduce the revive-llvm-builder crate with the revive-llvm builder utilty. - Do not rely on the LLVM dependency in $PATH to decouple the system LLVM installation from the LLVM host dependency. - Fix the emscripten build by decoupling the host and native LLVM dependencies. Thus allowing a single LLVM emscripten release that can be used on any host platform. - An example Dockerfile building an alpine container with a fully statically linked resolc ELF binary. - Remove the Debian builder utilities and workflow.
