Auto merge of rust-lang#131429 - Zalathar:needs-profiler-runtime, r=jieyouxu

Rename directive `needs-profiler-support` to `needs-profiler-runtime`

The rest of the compiler mostly refers to this as `profiler_runtime`, so having a directive named `needs-profiler-support` was causing a lot of confusion.
