Auto merge of #75697 - lzutao:mir-dumb-const-prefix, r=oli-obk

Suppress "const" prefix of FnDef constants in MIR dump

I [was asked][1] to suppress the `const` infront of `FnDef`.
I tried to suppress comments for other types, but turned out that `const ()` and `()` is different: https://github.com/rust-lang/rust/pull/75697#discussion_r473892806
