.vscode/settings.json: extract common settings

Move the 'editor.wordWrap = false' and 'files.trimTrailingWhitespace = true'
settings into a general scope from their previous language-specific
configuration. These represent the default values we want for any language.
These settings can still be toggled on a language-by-language basis if
necessary in the future.
