avutil: attributes: fix AV_HAS_STD_ATTRIBUTE checks
Attributes with the language-supported [[attr]] style are only supported
since C++11 and C23 respectively, so this needs to be accounted for in
these checks.
This solves a huge amount of warning spam of:
warning: [[]] attributes are a C23 extension [-Wc23-extensions]
when using --enable-extra-warnings.
(cherry picked from commit cce545a74b84ca64eb0c3e8e9aa8ea10dda2a066)
