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.

F18 was sigalling an end-of-file error condition when reading an
unformatted sequential input file without an ultimate newline
(or CR-LF). Other Fortran implementations can handle it, so change
the runtime to support it.

Extend the raw file wrapper to get accessibility, positioning,
and size information. This is needed for INQUIRE (to follow).

Anonymous Fortran unit files (e.g., "./fort.7") need to be created
O_RDWR so that they can be written, rewound, and read. Other
files opened with no ACTION= specifier need to set read/write
permissions based on the file, if it exists.

Add a data member knownSize_ and an accessor to allow the size of
an external file to be tracked when known. Also add a wrapper for
::isatty() here in the filesystem encapsulation module. These
features are needed for the external I/O rework changes still
to come.

New<A> used to return an A&; now it returns an OwningPtr<A>
to force better ownership tracking of allocations. Its API
has also been split into New<A> and SizedNew<A> to allow
allocations with a size override.
