Summary: Port libFuzzer to windows-msvc. This patch allows libFuzzer targets to be built and run on Windows, using -fsanitize=fuzzer and/or fsanitize=fuzzer-no-link. It allows these forms of coverage instrumentation to work on Windows as well. It does not fix all issues, such as those with -fsanitize-coverage=stack-depth, which is not usable on Windows as of this patch. It also does not fix any libFuzzer integration tests. Nearly all of them fail to compile, fixing them will come in a later patch, so libFuzzer tests are disabled on Windows until them.
