* [vcpkg docs] Change how documenting port functions works
Instead of using `##`, use comment blocks for documentation.
Also, add some minor docs and change RST -> MD
so we actually get docs generated.
* add CI stuff
* regenerate docs
* fix vcpkg_find_acquire_program to not use _execute_process
* [vcpkg] Track hashes of cmake script helpers in consuming portfiles
* [vcpkg] Format
* [vcpkg_find_acquire_program] Use cpkg_from_sourceforge for FLEX and BISON
