`ComponentId` system param

[lotus128]

What problem does this solve or what need does it fill?

Currently, we get ComponentId using World::component_id. This is not ideal, because that requires an exclusive system with a World system param.

What solution would you like?

I want a new system param for a ComponentId so that I can use ComponentId in a non-exclusive system.

What alternative(s) have you considered?

For now, I will use type id.

Additional context

I need this because I don't want to use generics type parameter for components.

Am I missing something or what you're asking is already satisfied by ComponentIdFor?
