meson: replace global_source_root/global_build_root with project_*

Browse source 
global_source_root() and global_build_root() typically shouldn't be used
in case the current project can be used as a subproject as it'll return
the path to the main project[1][2].

Instead, let's do as suggested by the documentation and use
project_source_root() and project_build_root() instead.
