[src/tests] Fix consistency between ObsoletedOSPlatform and UnsupportedOSPlatform attributes.

[rolfbjarne]

• If there's both an UnsupportedOSPlatform and ObsoletedOSPlatform attribute with
  the same version, then remove the UnsupportedOSPlatform attribute. This is because
  in the past we used [UnsupportedOSPlatform] + [Obsolete] to indicate that an API
  is obsolete, but then the [ObsoletedOSPlatform] attribute was added, and we replaced
  the [Obsolete] attributes with [ObsoletedOSPlatform] attributes, which makes the
  [UnsupportedOSPlatform] attributes redundant/incorrect.
• If there's [UnsupportedOSPlatform] with a version or [ObsoletedOSPlatform] with
  a version, then also add [SupportedOSPlatform] in a few cases.
• If there's an [UnsupportedOSPlatform] with a version for API that's obsolete/non-working,
  then remove the version.
