[tools] Remove deprecated scripts for Node

These scripts are not used nor maintained anymore by V8.
We use https://chromium.googlesource.com/v8/node-ci/.

Node.js is now taking ownership of these scripts:

-# Node.js Backports
-
-We no longer maintain our own backport script.
-
-For backporting V8 changes to Node.js, there is a useful script in
-[node-core-utils][1]. You can use the `git node v8 backport` command, which will
-bump the necessary V8 version numbers depending on the specific branch.
-
-See the [Node.js documentation][2] on V8 backports for a guide.
