Add const template parameter to get the precise lib type

[timotheeguerin]

Found those issue when working on uri template, splitting it from the uri template PR as its not really related.

Basically when using createTypeSpecLibrary({...} as const its not the same as doing

const libDef = {...} as const;
const $lib = createTypeSpecLibrary(libDef);

In the first case the paramMessage format param are not typed so we are missing errors which are fixed in this PR.
