[LibFuzzer] Add Windows implementations of some IO functions.

This patch moves some posix specific file i/o code into a new
file, FuzzerIOPosix.cpp, and provides implementations for these
functions on Windows in FuzzerIOWindows.cpp.  This is another
incremental step towards getting libfuzzer working on Windows,
although it still should not be expected to be fully working.
