All of these simp lemmas are also declared in core.
Maybe one of the copies can be removed in a future PR, but this PR is just to remove the duplicate simp attributes.
This is part of fixing linting problems in core, done in leanprover-community/lean#545.
Most of the duplicate simp lemmas are fixed in
core
, but I prefer to remove the simp attribute here in mathlib if the simp lemmas were already used in core.
