Move tar outside of dependencies

[TwistedTwigleg]

Description of changes:

Mirror of https://github.com/awslabs/aws-crt-nodejs/pull/335 but merged with latest changes in main and the package lock regenerated with npm.

Moves cmake-js and tar outside of dependencies and modifies the build script to download tar and cmake-js, use it, and store it in a sub-folder for reuse that is completely separate from the main node modules. This prevents cmake-js and tar from sticking around when it is only needed for building the source and not in the functionality of the CRT itself (and in the case of tar, it is needed only for a single download once to get the source).

With this change, cmake-js and tar is not sticking around in the node dependencies forever when it is only needed for build-time operations.

Wait on merging even if CI is successful for now - need to double check things.
