Create module registry: update build to add installModules array to p…

…bjs global (prebid#6601)

* - Remove module list comment on build
- Add pbjs.installedModules with macro to prebid.js
- Update gruntfile to replace macro with module array (if empty array all modules included))

* Removed unused code

* Removed comma

* Recommitting changes

* Updated regex to look for either '|" in macro name. Seems there is a difference between dev/prod
