Wine uses Mono's embedding API to replace MS .NET when it is available. Some
Windows programs (correctly) install assemblies to
c:\windows\assemblies\GAC_MSIL. These programs must be able to find the
installed assemblies to function.

With the current embedding API, including the MONO_GAC_PREFIX environment
variable (which in this case unhelpfully appends /lib/mono/gac to the path
given), it is impossible for Wine to ask Mono to search this directory.

To fix this problem, I would like to ask for an API function that Wine can use
to supply a GAC path for Mono to search, without having mono append
/lib/mono/gac.

I'm attaching a patch for this, and I've verified that it's usable for this
purpose. To avoid adding more special cases, I've reused extra_gac_paths and
changed its meaning so that it includes lib/mono/gac when needed (i.e. when it
is set from the MONO_GAC_PREFIX environment variable). I have not yet verified
that MONO_GAC_PREFIX still works properly, as I do not have a good test case
handy.

Reproducible: Always
