    meson: Fix generation of various sources
    
    Enumtypes are generated from gr-diet.h, not gr-recipe.h
    
    cuisine.css is generated at configure-time from cuisine.css.in
    
    segments.inc, ingredients.inc, no-ingredients.inc are generated using
    `sed` in Autotools, but this is not cross-platform-compatible, so use
    a Python script for it. This is also simpler to understand and bypasses
    potential string quoting/escaping issues.
    
    compile_resources needs a unique `c_name:` or there will be a symbol
    redefinition error.
    
    The target name of gdbus_codegen is used to generate the .h and .c
    files, so use the same name as Autotools and add it to the list of
    sources.
