ToDo: return support for clang on Windows

[q4a]

Is your feature request related to a problem? Please describe.

I would like to keep current problems with clang on Windows in this place. Current problems clang on Windows:

1 - clang build failed with crashpad

PR: https://github.com/storm-devs/storm-engine/pull/58 build log: https://github.com/storm-devs/storm-engine/runs/2403689592?check_suite_focus=true#step:5:576 logs_214.zip

This bug may be related: https://github.com/conan-io/conan-center-index/issues/96 But people says, that openssl/1.1.1c works fine with clang 8 + ninja: https://gist.github.com/uilianries/b114b80aff1c7f8eb5b2e2ae0bd7fd9e

2 - clang build failed with sdl 2.0.14

I replaced old PR, but has tree here: https://github.com/q4a/storm-engine/tree/fb484bbc50dee4f980918b595e633e7da7d6f704 build log: https://github.com/q4a/storm-engine/runs/2312924402?check_suite_focus=true#step:5:470 logs_78.zip

This bug related and fixed: https://github.com/libsdl-org/SDL/pull/4269 So, I hope to see fix in SDL 2.0.16: https://libsdl.org/next.php

Clang commits to revert:

https://github.com/storm-devs/storm-engine/commit/586c89a2fb874d2b9d99c395add800439ea3472d - return clang to CMakeSettings.json https://github.com/storm-devs/storm-engine/commit/adf1553649c6d1ef1e6f32ac05654632286649b9 - return clang to cibuild.yml

Describe the solution you'd like

I would like to:

1. Wait for SDL 2.0.16 release.
2. Add SDL 2.0.16 to bincrafters like this: https://github.com/bincrafters/community/commit/a60c4af61208799298b21bb3b797ae6efdd236da
3. Return clang build on Windows and check errors. May be I can found some fix for crashpad/openssl build.

[espkk]

We definitely want to turn it back after we find a solution to make it work.

To the point, OpenSSL is likely sentry-native and not a crashpad dependency as crashpad is currently included as a binary blob. Since Conan's sentry-native package is anyway broken, I'll try to find a way to set up our own artifactory package with proper configuration and probably different OpenSSL version (though I don't really like downgrading security libraries).

UPD: yeah, that openssl is a dependency for libcurl/7.75.0 which sentry-native depends on. but 1.1.1c is too old, maybe we should investigate the problem with more recent versions
