Scott Graham 9ab4fbf1e1 win: Improve child crash location test
In setting up the gn build, slightly different optimization settings
were applied for release builds. This caused a couple things to happen,
1) the sketchy noinline declspec was ignored, and 2) the distance
between reading the IP and the actual crash exceeded the tolerance of 64
bytes in the parent.

To make the test more robust to this, use CaptureContext() (I think our
improved version didn't exist at the time the tests was originally
written). Also, switch from crashpad::CheckedWriteFile to Windows'
WriteFile(), which avoids inlining a whole lot of code at that point.
The return value is not checked, but the next thing that happens is that
the function crashes unconditionally, so this does not seem like a huge
problem.

Bug: crashpad:79
