chore(windows): add sentry traces for unsolved crashes

Adds Sentry breadcrumbs for the following crash reports:
* KEYMAN-WINDOWS-62
* KEYMAN-WINDOWS-6H (? no reports in recent releases, so may be
  resolved)
* KEYMAN-WINDOWS-7J
* KEYMAN-WINDOWS-4R

The source of these crashes is hard to pinpoint, so hoping that this
additional data sheds some light.
