Michael Kruse cbad57613e [flang][msvc] Fix external-io unittest. 
Fix the external-io unittest under Windows.

In particular, fixes the following issues:

 1.  When creating a temporary file, open it with read+write permissions
     using the _O_RDWR flag. _S_IREAD and _S_IWRITE are for the file
     permissions of the created file.

 2. _chsize returns 0 on success (just like ftruncate).

 3. To set a std::optional, use its assign-operator overload instead of
    getting a reference to its value and overwrite that. The latter is
    invalid if the std::optional has no value, and is caught by
    msvc's debug STL.

The non-GTest unittest is currently not executed under Windows because
of the added .exe extension to the output file: external-io.text.exe.
llvm-lit skips the file because .exe is not in the lists of test
suffixes (.test is). D105315 is going to change that by converting it
to a GTest-test.
