[Windows] Enable crash reporter on MinGW builds.

[bruvzg]

Enables crash reporter on MinGW builds, stack trace will be readable only if converted *.pdb symbols are provided (e.g., generated from the DWARF symbols used by GCC using this tool - https://github.com/rainers/cv2pdb).

MinGW crash log generation seems to take more time (few seconds vs instant for MSVC) and include some unnecessary frames (since snapshot is taken by our crash handler not by SEH handler).

MSVC crash log example

Found a better way, without symbols conversion. I'll open a new PR soon.

New version - #61006
The only downside, it's not working with ASLR enabled, but this should not be an issue for debug builds. (Fixed)
