[iwyu] Add postprocessing to handle gtest/gmock include paths
Unfortunately, clangd's include-cleaner has a smaller set of
customization features and does not allow us to set custom mappings for
certain include paths. Instead, add some postprocessing to our internal
wrapper on top of it (`apply-include-cleaner`) to handle gtest/gmock
include paths
