Const-referencing for extra_args and env in catch2 tests
From !1197 (comment 1899201278):
Also, in lots of places we are passing the env vector by value. I guess you are copying the extra_args vector I added in those places. Do these need to be passed by value or was this just a typo on my part?
Needs !1263 (merged).
