Added dependency injection/easy registration for async filters

[tofi92]

Async filters (#2938) could not be registered with the SwaggerGenOptions, so there was no way of using DI with async filters.

I extended the SwaggerGenOptions for all the async filters and also added extension methods similiar to the sync equivalents, so added async filters is now as intuitive as sync filters, e.g. swaggerGenOptions.DocumentAsyncFilter<MyAsyncFilter>().

I was very say today when I converted a bunch of filters to be async and then couldn't register them without a bunch of ceremony. I definitely would like this to make it in in some form!

Thanks for your contribution - this looks good.

Could you bump the version to 6.8.0 as we're adding new public API members please? Then this looks good to merge.
