patch 9.1.0630: MS-Windows: build fails with VIMDLL and mzscheme
Problem: MS-Windows: build fails with VIMDLL and mzscheme
Solution: define scheme_register_tls_space() inside gvim.exe
and refer to it from the dll (Ken Takata).
`scheme_register_tls_space()` doesn't support a thread-local variable in
a DLL:
https://docs.racket-lang.org/inside/im_memoryalloc.html#%28cpp._scheme_register_tls_space%29
closes: #15363
