Remove simulacrum

[BalmungSan]

This is a dumb search and replace and is mostly intended as a conversation starter and maybe as a base for someone else to pick up and finish more advanced changes.

For context, see the following PRs where instructions to run scalafix simulacrum in the Cats' sources were more trouble than help.

• Add mapAccumulate to Traverse #4209 (comment)
• added ifF to Functor #4146 (comment)

See also plans to enable "organize imports" and other helpful CI-verified scalafixes via sbt-typelevel, which would have friction with the simualcrum scalafixes in this repository.

• Add Scalafix integration sbt-typelevel#274

Nice that this can be removed without a Mima issue.

We can also remove this file.

cats/.scalafix.conf

Lines 1 to 10 in 15f75f7

	rules = [
	AddSerializable
	AddImplicitNotFound
	TypeClassSupport
	]
	TypeClassSupport.opsObjectDeprecation = {
	message = "Use cats.syntax object imports"
	since = "2.2.0"
	}

I just removed more references to simulacrum.

Thank you for spear-heading this change.
