[clang-tidy] Simplify readability checks to not need ignoring* matchers

[njames93]

Please address the format issues.

clang-tools-extra/clang-tidy/readability/UniqueptrDeleteReleaseCheck.cpp

41–42

This allOf matcher only contains 1 sub matcher so is breaking the build.

Please rebase, this check has since been removed from clang-tidy.
