[0.4.11][JSCRIPT] Fix regression CORE-13810 "Vypress Chat 2.1.9 MSI setup fatal error"

The regression was unhidden by MSI-winesync 1.5.10 almost 7years ago:
8939969e21ddd1472e64596e11dee2ab58c9025e == SVN r57070

Finally we can fix it by adding MS enumerator extension to Jscript.

fix picked from commit 0.4.12-RC-18-g 9ebb42a4c01db05bb50be72fcfa49bd7a5a6afe4

It went afterwards into master in slightly modified form as 0.4.13-dev-890-g 83dcae1
But I decided to take the older state from 0.4.12RC, so that I do not have to risk
touching releases/0.4.12 again to sync to "latest&greatest".
