Normalize the 15 existing guards to the documented two-level form
get(g:, 'X_recommended_style', get(g:, 'filetype_recommended_style', 1)):
fix the two non-standard "!exists() || != 0" guards (python, arduino) and
tolk's wrong fallback variable, and convert the simple one-level guards.
Add the guard to filetype plugins that set stylistic indentation/format
options without one: aap, abap, ada, cabal, cobol, elixir, falcon,
graphql, heex, idris2, mermaid, occam, racket, scala, swift, tera.
Settings that are required rather than stylistic are left untouched, e.g.
make/gomod/scdoc (mandatory tabs), chatito and vroom (indent mandated by
the format), and the textwidth/formatoptions cases in gitcommit/help/
jjdescription.
