Use |isolate| local variable in bindings, clean up comments

Use |isolate| local variable in bindings, clean up comments

This removes 6 FIXMEs, and removes duplicate calls of info.GetIsolate().

This updates the license block to the new form (since this is *generated* code),
and makes it automatically use the correct module name.
I didn't make the year update automatically, as otherwise r-b-t will break
every new year and this detail doesn't seem worth the hassle.

I also moved one long comment into a template comment, so it's not in the
generated code. This seems clearer (it's in the template), and reduces
duplication and noise.

Overall these reduce the size of the generated code and tests
by about 6% (generated code from 17 MB from 16 MB)!
Not a big deal, but makes them a bit faster to compile and easier to read.

Some cleanup.

LGTM.

Looking at the CL, you might want to reduce # of run-bindings-tests :)

Yup, that's next.
We still need many of them, but at least the *Python duplication can go away.
