Switch to CMake and fix compilation with VS2022

This has been on my personal roadmap for a while, but wanted to add an issue to track it.

• Add a CMakeLists.txt in parallel to x64dbg.sln
• Support VS2022:
  • Fix all warnings
  • Fix Visual Studio analyzer results
• Add TitanEngine/GleeBug as submodules
• Add an option to automatically download a supported Qt5 LTS version (VS2019)
• Integrate clang-tidy
• Clean up the project root
• Support “offline” builds (ready-to-compile source package)
• Create an external plugin for Scylla (latest fork)
• Upgrade dbghelp.dll and msdia140.dll to the latest version
• Restore delayed imports
• Restore signing functionality for latest MSVCRT
• Remove TitanEngine/DeviceNameResolver and other internal libraries from the pluginsdk
• Update compilation instructions in the wiki
• Update the QtPlugin template and PluginTemplate
• Delete the old .vcxproj and x64dbg.pro files
• Fix the relative submodule path when forked (url = ../../x64dbg/deps)
• Make sure the exe project is the default startup project in the generated solution
• Update CONTRIBUTING.md to match the new workflow
• Remove licenses from docs folder and pull them dynamically during the build to avoid multiple licenses being detected for the repository
