Turned match-requires dependency into helper to remove core-js deprecation warnings

Removed a dependency, added code from dependency directly into the project, installed and updated other dependencies

Removed match-requires as a dependency by putting its code into a helper file. Installed the two dependencies it was using as root dependencies for reactor-packager. The updated versions removed the usage of core-js which removed that warning. Also bumped shelljs and path-pars to the latest versions.

Motivation and Context

This removes the core-js warning when doing a fresh npm install.

How Has This Been Tested?

Tested this by packaging a few different extensions to make sure they packaged correctly as well as running the local tests.
