after this commit:
Worker disable is no longer supported by pdfjs since version 2.0, so
remove disabling worker code.
Used pre-built version of pdfjs as source version dependency with other
lib like SystemJS and we can not add dependency of these libs, so used
pre-built version which don't require any other dependent lib.
pdf.worker.js is always loaded and as we are using pre-built version we
don't need odoo's loader, previously we need it because worker loader of
pdfjs was loading files separately so to avoid it as we were loading
files in asset bundle we had odoo's loader file but we don't need it
anymore.
