Auto merge of #104824 - klensy:bump-some, r=Mark-Simulacrum

deps: update cpufeatures, swap difference to dissimilar

Updating cpufeatures v0.2.1 -> v0.2.5: https://github.com/RustCrypto/utils/blob/master/cpufeatures/CHANGELOG.md#025-2022-09-04, was yanked bc of miscompile (https://github.com/RustCrypto/utils/pull/800, https://github.com/rust-lang/rust/issues/101346)

Removing difference v2.0.0
     Adding dissimilar v1.0.4
   Updating expect-test v1.0.1 -> v1.4.0

difference unmaintened https://rustsec.org/advisories/RUSTSEC-2020-0095.html, so replaced with https://github.com/dtolnay/dissimilar (as dependency of `expect-test`)
