Refactor ANGLE's extensions struct to more easily represent multiple

vendor extension Some extensions are available from multiple vendors with the same name, while minimizing the amount of duplicated code and validation errors. The anonymous struct allows individual vendor checks as well as an "*Any()" check to check for any version of the extension.
