Fix T79801: openvdb cache does not support Unicode paths on windows
"Fix" should be taken with a grain of salt, this will fix
the issue on win10 1903 and newer.
OpenVDB uses boosts memory mapped files which call
CreateFileA in the back-end when you feed it a
regular string.
now the encoding for CreateFileA will be whatever the
default is for the system, it internally turns it into
a wide string with said encoding and calls CreateFileW.
This change changes that encoding to UTF-8 for just
blender so we can use utf-8 with any of the narrow
api functions. This is a manifest change and only win10
1903 will look for it, so that sadly limits the fix
to only a subset of users.
While ideally we would have fixed the issue our selves,
some of the calls to openvdb::io::file::open are beyond
our control (ie from inside USD or Mantaflow)
Note: This only changes the behaviour in regard to Win32
API functions, regular CRT functions like fopen or if_stream will
still not accept utf-8 filenames.
