Eolian/Generator: don't generate legacy if legacy_prefix is "null".

For new classes that don't need legacy, instead of setting legacy null
for all the functions, legacy_prefix can be set to "null" to not
generate legacy.
However, if, for example, only one function among 50 need legacy, you
can specify it by setting for this function the legacy token.
