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
