## Feature objects now have an enable_auto_if method

This performs the opposite task of the disable_auto_if method, enabling the
feature if the condition is true.
interpreter: add a feature.enable_auto_if It's always been strange to me we don't have an opposite method of the `disable_auto_if` method, but I've been pressed to find a case where we _need_ one, because `disable_auto_if` can't be logically contorted to work. I finally found the case where they're not equivalent: when you don't want to convert to a boolean: ```meson f = get_option('feat').disable_auto_if(not foo) g = get_option('feat').enable_auto_if(foo) dep1 = dependency('foo', required : f) dep2 = dependency('foo', required : g) ``` 2 years ago			`## Feature objects now have an enable_auto_if method`
