[PATCH v2 3/9] cache.h: extract enum declaration from inside a struct declaration

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

While it is technically possible, it is confusing. Not only the user,
but also VS Code's intellisense.
