Subject: [PATCH 1/2] fix(dasp_signal): make it build again without `std` on
 the latest nightlies

Rust PR https://github.com/rust-lang/rust/pull/160989, which is already
part of the latest 1.100 nightlies, changed several unstable
`core::intrinsics` functions to be generic, which implied a breaking
name change. Unfortunately, these are used by `dasp_signal` when the
`std` feature is not enabled.

These changes make `dasp_signal` use the new intrinsic names, so that
builds without the `std` feature work again on the latest nightlies.
People that have to keep using older nightlies for any reason may
temporarily pin their dependency on `dasp_signal` to a version
compatible with their nightly build.

While at it, I have also realized that such intrinsics have not been
unsafe for a while now, so I removed their surrounding `unsafe` blocks.
