ClangFormat: Replace checks widget with editor

The existing approach utilizing the widget poses maintenance
challenges, primarily due to the dynamic nature of clang-format
settings across versions. The widget necessitates regeneration
for each new version, and compatibility issues arise when users
have different clang-format versions on their devices.

The updated solution adopts an Editor integrated with a yaml
language server, offering the ability to highlight and provide
code completion for the .clang-format file. This resolves the
widget regeneration issue and ensures compatibility with various
clang-format versions.

- Replaced the checks widget with an editor
- Introduced a line for yaml language server schema
in .clang-format files to enable autocompletion.
ToDo: Enhance schema accessibility without relying on this line.
- Added Ctrl+Space shortcut for autocompletion
- Added Ctrl+S shortcut for saving
- Eliminated outdated logic related to the checks widget
- Fixed copying and removal of clang-format settings
