[dev.boringcrypto] crypto/internal/boring: update BoringCrypto module to certificate 3678

Replace the chroot scaffolding with Docker, which brings its own caching
and works on macOS.

Fixes #40188

We have been working inside Google on a fork of Go that uses
BoringCrypto (the core of [BoringSSL][]) for various crypto
primitives, in furtherance of some [work related to FIPS 140-2][3318].
primitives, in furtherance of some [work related to FIPS 140-2][sp].
We have heard that some external users of Go would be interested in
this code as well, so this branch holds the patches to make Go use
BoringCrypto.

Unlike typical dev branches, we do not intend any eventual merge of
