  [JSC] Refine SyntaxError message for generator method parsing failure
https://bugs.webkit.org/show_bug.cgi?id=264368
<rdar://problem/118081884>

Reviewed by Justin Michaud.

This change rewords SyntaxError message, thrown in case of generator method parsing failure,
to mention "method" rather than "function", aligning error wording for sync generator functions
with async counterparts.

Also, tweaks the helper to return "generator function" instead of "generator" for GeneratorBodyMode,
which is unobservable yet matches the terminology of the spec [1].
