[PATCH 07/16] cache.h: remove expand_user_path()

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

expand_user_path() was renamed to interpolate_path() back in mid-2021,
but reinstated with a #define and a NEEDSWORK comment that we would
eventually want to get rid of it.  Do so now.
