add compile_commands support to simplify development

[wbpcode]

This patch added a tool to generate compile_commands.json file. Then we can enable the auto complete, go-to-definition, etc. of clangd.

Thank https://github.com/hedronvision/bazel-compile-commands-extractor for it provide the great script/tool to make this so easy!
