Rollup merge of #129201 - joboet:random_faster_sources, r=joshtriplett
std: implement the `random` feature (alternative version) Implements the ACP rust-lang/libs-team#393. This PR is an alternative version of #129120 that replaces `getentropy` with `CCRandomGenerateBytes` (on macOS) and `arc4random_buf` (other BSDs), since that function is not suited for generating large amounts of data and should only be used to seed other CPRNGs. `CCRandomGenerateBytes`/`arc4random_buf` on the other hand is (on modern platforms) just as secure and uses its own, very strong CPRNG (ChaCha20 on the BSDs, AES on macOS) periodically seeded with `getentropy`.
