base::Pipe: Use HANDLE on Windows This CL switches base::Pipe from using the POSIX-compat API _pipe() to CreatePipe(). Turns out that is more proper for use in base::Subprocess (which will be introduced by an upcoming CL) because CreatePipe() returns objects that can be waited for using WaitForMultipleObjects, and hence by the TaskRunner. This CL also: - Fixes ScopedPlatformHandle on Windows. Turns out both nullptr and 0xffff... are invalid values. - Introduces some file_utils methods to Read/Write from HANDLEs. Test: ran perfetto_unittests on Win and Linux. Bug: 174454879 Change-Id: Ic8b51821a5909857ddb437b02de3e642594453af
