Following https://llvm.discourse.group/t/psa-ods-generated-accessors-will-change-to-have-a-get-prefix-update-you-apis/4476, this follows flipping these dialects to _Both prefixed form. This changes the accessors to have a prefix. This was possibly mostly without breaking breaking changes if the existing convenience methods were used. (https://github.com/jpienaar/llvm-project/blob/main/clang-tools-extra/clang-tidy/misc/AddGetterCheck.cpp was used to migrate the callers post flipping, using the output from Operator.cpp) Differential Revision: https://reviews.llvm.org/D112383
