This is blocking rust-lang/rust#117372, which replaces `stdsimd` with more fine-grained features. However the auto-detection in aHash breaks when bootstrapping Rust because it detects the `stdsimd` feature on the old toolchain which is not present on the newly build libcore. This PR removes the build-time detection of the `stdsimd` feature and instead just uses the ARM AES intrinsics directly since they are now stable, but only on AArch64.

AHash just released a new version, so this should be unblocked now.

…ly (#6) * use newly introduced stdarch features for avx512 to compiler on nightly see rust-lang/rust#117372 * bump version to 0.18.7

Specifically, i'm hitting tkaitchuck/aHash#200 ahash FTBFS because of rust-lang/rust#117372 which is fixed in 0.8.7. This rolls us forward which should fix future builds.

Rust has removed the `stdsimd` feature: rust-lang/rust#117372 This broke `ahash` for versions prior to `0.8.7`: tkaitchuck/aHash#183

Previous versions use the `stdsimd` nightly feature if it detects that it is available (on a nightly toolchain). This will stop working once rust-lang/rust#117372 is merged.

The newest Rust nightly removed the `stdsimd` feature in favor of more grained features (rust-lang/rust#117372). However, the version of `ahash` we depend on, still requires that feature. New release of `ahash` (0.8.7) contains a fix, but we can't upgrade to it without upgrading Anchor. Pinning Rust nightly seems to be the less intrusive solution for now.
