[V8] Rename constructorCallbackCustom() to constructorCustom()
https://bugs.webkit.org/show_bug.cgi?id=110671

Reviewed by Adam Barth.

his is one of steps to insert TRACE_EVENT_STATE() macros
into DOM bindings.
See https://bugs.webkit.org/show_bug.cgi?id=110667#c0

In the new world, "Callback" is used to indicate that it
is a function called back by V8. Currently "Callback" is
used for both V8 callbacks, DOM methods and DOM constructors.
This patch fixes the inconsistency.

No tests. No change in behavior.
