feat: Update Crashpad and register WER handler

[Swatinem]

Crashpad added a new WER (Windows Error Reporting) handler which needs
to be manually registered first in the Windows Registry, and then with
the crashpad client.

This depends on getsentry/crashpad#69

[Swatinem]

Good think our CI caught this:

• The Windows SDK used to build the projects needs to be at least version 19041 to provide the required header struct definitions.
• Other functions that crashpad calls are available since Windows 7.

We should be able to make all this conditional depending on the exact version customers want to target.
We had a couple of requests and PRs to support XP, but officially we don’t really guarantee support, so things could potentially break at any time if people are targetting XP.

Either way, I would wait for @supervacuus to be back to help with the correct cmake and ifdefs for conditional compilation here.

I see deprecation warnings with every test I run because support for regex strings without the r prefix is soonish unsupported. It requires python 3.6, though (released almost six years ago). I know we focus on compatibility, but maybe it is less complicated here, since this is only used by devs? Fine to change this in another PR.

those are some nice testsuite improvements!
