The clang-tidy-vs visual studio plugin in clang-tools-extra contains a
security vulnerability in the YamlDotNet package [1]. I posted to cfe-dev [2],
asking if there was anyone who was interested in updating the the plugin
to address the vulnerability. Reid mentioned that Zach (the original committer),
said that there's another plugin (Clang Power Tools) that provides clang-tidy support,
with additional extra features, so it would be ok to remove clang-tidy-vs.
This patch removes the plugin to address the security vulnerability, and adds
a section to the release notes that mentions that the plugin was removed, and
suggests to use Clang Power Tools.
