@SupportedLanguage support for symbols
Description
With https://forums.swift.org/t/setting-programming-language-availability-for-articles-in-swift-docc/61435, the @SupportedLanguage directive was added to specify the programming languages an article is available in. It would make sense to bring it to symbols as well as part of a future PR. The @SupportedLanguage data would override data from symbol graphs, similar to how the @Available directive overrides the symbol graph information.
Motivation
Provide the ability of overriding the programming languages a symbol is available in. In practice, the use cases for wanting this will likely be very rare and will likely not apply when building Swift+ObjC documentation.
Importance
No response
Alternatives Considered
We could decide to not support this directive for symbols, in which case we'd want DocC to emit a diagnostic explaining that the use of the directive is not supported for symbols.
