Bump the minimum supported MSVC version to VS2019

This aligns with https://github.com/google/oss-policies-info/pull/8 and
https://github.com/grpc/grpc/pull/32614. VS2019 adds a C11 mode, which
is useful for us, because it means stdalign.h works correctly.

Also bump the minimum Windows SDK to
https://devblogs.microsoft.com/cppblog/c11-and-c17-standard-support-arriving-in-msvc/.
If you have a new MSVC, CMake will enable C11 mode by default. But if
C11 mode is enabled but your Windows SDK is too old, things break.

After this change, the CI will include some redundant configurations.
All the VS2017 configurations will start testing on VS2019, so the
VS2019-specific configurations won't do anything. I'll follow this up
with a change to bump those to VS2022, where we're currently missing
coverage.

Update-Note: BoringSSL now requires VS2019 or later and no longer
supports VS2017. VS2017 has been past its "mainstream end date" for over
a year now, per

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.
