Rollup merge of #132015 - compiler-errors:move-const-trait-tests, r=fee1-dead

Move const trait tests from `ui/rfcs/rfc-2632-const-trait-impl` to `ui/traits/const-traits`

I found the old test directory to be somewhat long to name, and I don't think it's necessary to put an experimental implementation's tests under an rfc which is closed.

r? fee1-dead

Breaking this out of #131985 so that PR doesn't touch 300 files.
