RFR: 8354071: Add LintCategory property indicating whether @SuppressWarnings is supported [v2]

[Archie Cobbs]

> This is split off as a sub-task of [JDK-8224228](https://bugs.openjdk.org/browse/JDK-8224228), which seeks to add `@SuppressWarnings` support for lexical features.
> 
> Lint warnings that are subject to suppression via `@SuppressWarnings` must be deferred until attribution, because until then we can't determine whether they are suppressed or not.
> 
> Whether a lint warning is subject to suppression via `@SuppressWarnings` is a function of the associated `LintCategory`, not the warning itself. For example `LintCategory.OPTIONS` is not, so an occurrence of `@SuppressWarnings("options")` is meaningless and would be ignored.
> 
> This information is needed in the upcoming refactoring. We can facilitate that very simply by adding a boolean property to the `LintCategory` enum.
> 
> In addition, this permits a small optimization to be added to `Lint.suppressionsFrom()`.
