New TOC should be normaliseable to a TOC without pattern entries

[agoose77]

Description

The new TOC implements a pattern entry. This is really just shorthand for enumerating files, and we should not have to reason about patterns in our TOC handling logic

Proposed solution

Normalise a TOC to a TOC without patterns

[fwkoch]

There is now a step in the project processing that converts a toc into a toc without patterns. This isn't really visible or available externally, but I don't think it needs to be...? It's just an implementation detail that simplifies subsequent toc handling.
