Format web-sys bindings by default

Browse Source 
This commit switches to executing `rustfmt` by default on
`web-sys`-generated bindings. This improves situations like "view
source" in Rustdoc as well as the IDE interactive debugging experience.

This was initially disabled by default because `rustfmt` took so long to
execute, but nowadays `web-sys` is by default much smaller so there's
much less need to avoid running `rustfmt` in fear of it taking too
long.

Closes #1457
