[clang-tidy] suppress dump of disabled checks options when running --dump-config #146693
Description
When running clang-tidy --dump-config, the output includes CheckOptions for checks that are currently disabled in the Checks configuration. This creates unnecessary noise and can be confusing for users trying to understand their active configuration.
Need to filter out disabled check options: Only show CheckOptions for checks that are actually enabled in the current Checks configuration
Here is an example when running on LLVM codebase:
clang-tidy -p build --dump-config clang-tools-extra/clang-tidy/ClangTidy.cpp
