Add a pre-build script to convert YAML profile files to `.go` source files

I am thinking about a way to unify the format of built-in alignment profiles and custom profiles. An achievable way is to create YAML format profiles in the repository, and use a pre-build script to convert them into .go source files.

The pre-build script can be added to Makefile, as a dependency of task build and cross-build. For convenience reason, The script can be also written in a different language like Python.
