inno: replace add_path.exe with a Pascal script
While attempting to build the Inno installer, I was unable to
find a copy of add_path.exe from the source site previously
listed in the docs.
Some quick Googling revealed that achieving this functionality
in native Pascal scripts seems to be preferred these days.
This commit vendors "Modify Path" (fetched from
https://www.legroom.net/software/modpath) and plugs it into
our Inno config file per its instructions.
The existing Inno installer appears to only modify PATH for
the current user (as opposed to at the system level). I've
maintained this behavior with Modify Path. Although it would
be trivial to change or add checkboxes to control the behavior.
I'll leave this as a follow-up.
