[PATCH 4/5] cache.h: drop read_cache_preload(pathspec)

[Stefan Beller <sbeller@google.com>]

coccinelle patch:
@@ expression E; @@
-read_cache_preload(E)
+read_index_preload(&the_index, E)

Additionally manual editing:
* drop the define from cache.h.
* builtin/{commit,describe}.c were not picked up as we have NULL and
  the address of an expression. Converted them manually.
* builtin/diff{-files,-index}.c error messages converted as well.
