Description

Upgrade Doorstop to version 4.3.0. This fixes a regression where dnspy debugging broke on old mono. By the same token, it adds 2 features:

• It is now possible to redirect the untiy's boot.config file
• Doorstop debugging now works on old mono and dnspy debugging no longer requires a patched mono even if it is an old mono.

Motivation and Context

It fixes a regression where dnspy debugging broke on old mono and adds 2 interesting features that the new version of doorstop offers.

How Has This Been Tested?

I tested that the build system correctly obtained the new doorstop on all builds and tested in a unity 2018.4.12 game with 2 versions (one that released with old mono and another that released with new mono).
