Meta: Don't assume how each generator wants to generate keyed map names

Browse source 
The generate_mapping helper generates a series of structs like:

    Array<SomeType, 1> s_mapping_key_0 {};
    Array<SomeType, 2> s_mapping_key_1 {};
    Array<SomeType, 3> s_mapping_key_2 {};
    Array<Span<SomeType const>> s_mapping { {
        s_mapping_key_0.span(),
        s_mapping_key_1.span(),
        s_mapping_key_2.span(),
    } };

Where the names of the struct were generated by the format_mapping_name
lambda inside the helper. Rather than this lambda making assumptions on
how each generator wants to name its structs, add a parameter for the
caller to provide a naming formatter.

This is because the TimeZoneData generator will want pretty specific
identifier formatting rules.
