Simplify the external Bazel build. Now that all assembly files are conditionalized, we no longer need to detect platforms at the build level. This is convenient because detecting platforms in Bazel is a bit of a mess. In particular, this reduces how much we depend on @platforms being correct. gRPC's build appears to still be using some legacy modes which seem cause it to, on cross-compiles, report the host's platforms rather than the target. See https://github.com/grpc/grpc/pull/31938 gRPC should eventually fix this, but it is apparently challenging due to complexities in migrating from Bazel's legacy system the new "platforms" mechanism. Instead, try to sidestep this problem by not relying on the build to do this. Now, we primarily rely on os:windows being accurate, and cross-compiling to/from Windows is uncommon. We do also need os:linux to be accurate when Linux is the target OS, but if Linux is the host and gRPC mislabels the target as os:linux, this is fine as long as the target is not FreeBSD, Apple, or another platform that cares about _XOPEN_SOURCE. (In particular, Android is ambivalent.) I've also renamed a few things based on what they were actually selecting. posix_copts was really copts for toolchains with GCC-style flags. Unfortunately, it's not clear how to condition on the compiler, rather than the platform in Bazel, so we'll do the wrong thing on non-MSVC Windows toolchains, but that was true before.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
