base: Port subprocess to Windows Introduces a functionally-equivalent implementation of base::Subprocess for Windows. Unlike POSIX, the windows implementation is based on using blocking I/O and spawning two threads (one for draining stdout/err, one for pumping stdin). Using OVERLAPPED I/O on Windows is too complex (and also internally seems to use a thread pool anyways) and isn't worth the risk, given Subprocess is used only by tools/. The only changes introduced on Linux/Android/Mac are: - Changing the MovableState to be a unique_ptr. This make it safe to use from other threads across std::move. - Removing the kKilledBySignal state and folding it into kRunning. - Adding an explicit bool timed_out() operator. Test: perfetto_unittests.exe --gtest_filter=Subprocess* Bug: 174454879 Change-Id: Ifa6ace5c58cf043861f474fff98e798f7764fb69
