environment: remove the global variable 'core_preload_index'
The global variable 'core_preload_index' is used in a single function named 'preload_index()' in "preload-index.c". Move its declaration inside that function, removing unnecessary global state. This change is part of an ongoing effort to eliminate global variables, improve modularity and help libify the codebase.
