cmake: rename Find modules
- `FindCARES`   -> `FindCares`
- `FindLibPSL`  -> `FindLibpsl`
- `FindLibSSH2` -> `FindLibssh2`
- `FindQUICHE`  -> `FindQuiche`
- `Findrustls`  -> `FindRustls`

Our convention for naming Find modules (the part after the `Find`
prefix, also called as 'package name') is:

Always start with uppercase. Follow with lowercase, unless there is
a clear preference for a stylized name. E.g. the project itself uses it
that way with a matching `<Name>Config.cmake` file, or we use it that
way elsewhere, or the name is an acronym.

Ref: #14580

Closes #14601
