lib: make toHyprconf support strings and attrs in sections

Browse Source 
Adds support for

    section = [
      "abc"
      { a = 123; }
    ];

Which gets generated to

    section=abc

    section {
      a=123
    }

This is very useful with the new windowrule syntax, where you can
create anonymous window rules as strings and named rules as attribute
sets. See <https://wiki.hypr.land/Configuring/Window-Rules/>.
