[Format] Make it easy to add new format::FormatStyle::LanguageStandard. NFCI

MaskRay · MaskRay · commit 00e8ac3bebfa · 2019-07-24T08:04:29.000Z
Preparatory change for D65043. We current use `!=LS_Cpp03` to enable language standards 11,14,17, and 2a. `>=LS_Cpp11` is better if we decide to add new LanguageStandard in the future. Reviewed By: sammccall Differential Revision: https://reviews.llvm.org/D65183 llvm-svn: 366876
