[clang-tidy] Improved --verify-config when using literal style in config file (#85591)

Specifying checks using the literal style (|) in the clang-tidy config
file is currently supported but was not implemented for the
--verify-config options. This means that clang-tidy would work properly
but, using the --verify-config option would raise an error due to some
checks not being parsed properly.

Fixes #53737
