Retire the Windows BIO_printf workaround.

With the UCRT, introduced in VS 2015, vsnprintf in MSVC is now
C99-conformant. See:
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/vsnprintf-vsnprintf-vsnprintf-l-vsnwprintf-vsnwprintf-l?view=msvc-170

It is a little unclear to me whether "Beginning with the UCRT in Visual
Studio 2015 and Windows 10" means it is only C99-conformant in Windows
10, or if this is referring to how the UCRT starts becoming an OS
component in Windows 10. I think the latter. This document talks about
the UCRT:
https://docs.microsoft.com/en-us/cpp/porting/upgrade-your-code-to-the-universal-crt?view=msvc-170

But we have tests which cover this in BIOTest.Printf. If it's not
C99-compliant in Windows 7, we'll notice in Chromium's CI.

BoringSSL

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.
