Looks like this source generator is completely non incremental

[lsoft]

Looks like this generator (https://github.com/TelegramBots/Telegram.Bot/blob/843756aeb5cc8d8b94e30835d8c55ee5e98f2a7b/src/EnumSerializer.Generator/EnumConverterGenerator.cs#L24) is a part of widespread epidemic with incrementality failure.

You should never have any compilations or symbols in any steps of your incremental pipelines, and especially in output steps. Those objects are not equatable and not meant to be used this way.

@lsoft In our case this is not such a big problem since our source generator is internal and is not used by the wide public. We also don't have much expertise on source generators and how to properly fix this issue. If you have the necessary knowledge and are willing to help I'll be very grateful
