For #26623
- Updated `github.com/groob/plist` to `github.com/micromdm/plist` -- it
was renamed
- Added validation that restricts DigiCert Fleet variables to
`com.apple.security.pkcs12` payloads plus additional restrictions
- Added validation that restricts Custom SCEP Fleet variables to
`com.apple.security.scep` payloads plus additional restrictions
- Enabled multiple CAs (Fleet variables) to be present in an Apple MDM
profile. But each CA can only be used once. For example, we can have
DigiCert CA and Custom SCEP CA in one Apple profile.
