Cleanup: Remove github helper scripts.

Cleanup: Remove github helper scripts.

Blink on github is not supported, Blink lives in:
chromium.googlesource.com/chromium/blink/+/master.

So these scripts are from an era where Chromium was integrating WebKit,
but since we forked and created Blink, they don't make much sense
anymore.

I'm fine w/ removing these, but we should probably get abarth@ to review, since
he's the one that added them.

They were so beautiful!

Github still seems to be our best way to do experimental branches. :/

That said, I doubt these even work exactly as-is, so lgtm to remove.
