Fixes #2669 * Check capabilities when validating variables * validate load and store types * Constant check * Don't checks pointers for stores, constants and loads * Validate composite instructions * Validate conversions for 8- and 16-bit limited types * Unified tests and expanded them * Disallow OpCopyMemory * new tests and update old tests
