fix(format): reformat with the Code Style indent, not the detected one

Without a per-language Tabs and Indents override, Reformat Code asked the
language server for the indent detected in the file. A file indented with 2
spaces (e.g. formatted elsewhere with Google style) then reformatted to 2
spaces and reported "already properly formatted", while a new file got 4.
Reformat now always asks for the Code Style indent (EditorConfig included);
detection only affects editing, and an indent chosen for the file in the
status bar still applies.

Fixes #2467
