I don't know how this was introduced.

However, if you just want to know why such a wrapper is needed:
dvipdfmx changes it's behavior depending on the program name
it was called, e.g., it behaves as extractbb when "xdvipdfmx.exe"
is called through the wrapper "extractbb.exe".

I think this Windows specific behavior comes from the autoconf
macro "KPSE_WIN32_CALL" described in the following page:

  https://www.tug.org/texlive/doc/tlbuild.html#Macros-for-Windows

A wrapper is used just to emulate symbolic links on Windows
platforms.
