Fix hang in GC_free if GC_PREFER_MPROTECT_VDB (Mingw64)
(a cherry-pick of commit 0a32dd39a from 'release-8_2')
Disable MPROTECT_VDB for Mingw64 (mingw-w64-x86_64) because
SetUnhandledExceptionFilter() is not working proporly in this runtime
(GC_write_fault_handler is never invoked), at least as of Mingw64
x86_64-8.1.0-release.
* include/private/gcconfig.h [X86_64 && MSWIN32 && !__INTEL_COMPILER
&& GC_GNUC_PREREQ(4,7)] (MPROTECT_VDB): Do not define if __MINGW64__;
update comment.
