rts/win32: Exit with EXIT_HEAPOVERFLOW if memory commit fails

Since switching to the two-step allocator, the `outofmem` test fails via
`osCommitMemory` failing to commit. However, this was previously exiting
with `EXIT_FAILURE`, rather than `EXIT_HEAPOVERFLOW`. I think the latter
is a more reasonable exit code for this case and matches the behavior on
POSIX platforms.
