Refactor and add missing PreconfiguredMapping and isMapping

[bernhardmgruber]

Rename all meta functions PreconfiguredX, for all mappings X to BindX. Also rename the nested type alias template to fn. This makes LLAMA more coherent with other quoted meta functions.
This PR also adds missing isX detection functions for all mappings (except Trace/Heatmap) where missing.
