projects: Update VC version names for VS2017, VS2022

- Rename VC15 -> VC14.10, VC17 -> VC14.30.

The projects directory that holds the pre-generated Visual Studio
project files uses VC<ver> to indicate the MSVC version. At some point
support for Visual Studio 2017 (Visual Studio version 15 which uses MSVC
14.10) was added as VC15. Visual Studio 2022 (Visual Studio version 17
which uses MSVC 14.30) project files were recently added and followed
that same format using VC17.

There is no such MSVC version (yet) as VC15 or VC17.

For VS 2017 for example, the name we use is correct as either VS17,
VS2017, VC14.10. I opted for the latter since we use VC for earlier
versions (eg VC10, VC12, etc).

There is no need to test for both _WIN32 and WIN32 as curl_setup.h

Also tests/server/util.c is only checking for WIN32 arouund the
implementation of win32_perror, so just defining _WIN32
would not be sufficient for a successful compilation.

docs/opts: Mention Schannel client cert type is P12

Schannel backend code behaves same as Secure Transport, it expects a P12
certificate file or the name of a certificate already in the user's OS
key store. Also, both backends ignore CURLOPT_SSLKEY (tool: --key)
because they expect the private key to already be available from the
keystore or P12 certificate.
