git: T5803: Adjust git configuration for baseline defaults

Apply baseline defaults for `.gitattributes` and `.vscode/settings.json`
for improved developer experience.

The `.gitattrbutes` settings are based on:
Git documentation (https://git-scm.com/docs/gitattributes#_effects)
GitHub documentation (https://docs.github.com/en/get-started/getting-started-with-git/configuring-git-to-handle-line-endings)
Community templates (https://github.com/gitattributes/gitattributes)

Since editor-agnostic line-ending specific settings are applied to
`.gitattributes`, they can be removed from `.vscode/settings.json`.
The global VSCode defaults have also been removed to avoid duplication.
