WebCore::GlobalWindowIdentifier Initialize processIdentifier
https://bugs.webkit.org/show_bug.cgi?id=242517

Reviewed by Darin Adler.

We need to initialize processIdentifier as it is accessed by the
equality operator for GlobalWindowIdentifier.

Fixes the following valgrind error:

The change log entry isn’t great. Pasting an entire backtrace in there is not all that helpful. Also should mention valgrind and explain why this change helps. But the code change is fine.
