Revert exclusion of `clang-compiler-activation-feedstock`

[JeanChristopheMorinPerso]

It looks like I went a little bit too crazy on excluding stuff. clang-compiler-activation-feedstock is actually needed to get clang_{target_platform} and friends.

If I run percy recipe outdated -s osx-arm64 I get this error:

Is it something broken? Or are my configurations/installation somehow not well done?

@skupr-anaconda it seems unrelated to me.
