Update pdf.js to 2.5.207 (#3222)

* updated pdf.js to 2.5.207, and added worker-loader as a devDependency
* updated pdf.js loaded to load ES5 build instead of the default one
* replaced imports with named imports due to changes on pdf.js worker loading

There are some hash downgrades in the lockfile. Running the commands through the appropriate methods yields the same result consistency
