Rollup merge of #60316 - mgeier:rename-capacity-parameter, r=joshtriplett

Use "capacity" as parameter name in with_capacity() methods

See #60271.

The only place where I didn't change the parameter name is `RawVec`. The problem is that it has a `.cap()` method instead of the usual `.capacity()`:

https://github.com/rust-lang/rust/blob/597f432489f12a3f33419daa039ccef11a12c4fd/src/liballoc/raw_vec.rs#L200-L210

Changing this would be a breaking change, and I guess that's not worth it.

But since I didn't change `.cap()` there, I didn't change the `cap` parameter name to `capacity`, either.
