We encourage users to generate visual studio project files using CMake.

We keep project files in git for ancient visual studio versions that
cmake cannot generate files for, but we no longer ship the project files
in the tarballs.

Windows projects included VC14, VC14.10, VC14.30 but not VC14.20.
OpenSSL and Wolf SSL scripts mention VC14.20 so I don't see a reason why
this is missing. Updated the templates to produce a VC14.20 project.

tool: add "variable" support

Add support for command line variables. Set variables with --variable
name=content or --variable name@file (where "file" can be stdin if set
to a single dash (-)).

Variable content is expanded in option parameters using "{{name}}"
(without the quotes) if the option name is prefixed with
"--expand-". This gets the contents of the variable "name" inserted, or
a blank if the name does not exist as a variable. Insert "{{" verbatim
in the string by prefixing it with a backslash, like "\\{{".

Import an environment variable with --variable %name. It makes curl exit
with an error if the environment variable is not set. It can also rather
get a default value if the variable does not exist, using =content or
@file like shown above.

Example: get the USER environment variable into the URL:

--variable %USER
--expand-url = "https://example.com/api/{{USER}}/method"

When expanding variables, curl supports a set of functions that can make
the variable contents more convenient to use. It can trim leading and
trailing white space with "trim", output the contents as a JSON quoted
string with "json", URL encode it with "url" and base 64 encode it with
"b64". To apply functions to a variable expansion, add them colon
separated to the right side of the variable. They are then performed in
a left to right order.

Example: get the contents of a file called $HOME/.secret into a variable
called "fix". Make sure that the content is trimmed and percent-encoded
sent as POST data:

--variable %HOME=/home/default
--expand-variable fix@{{HOME}}/.secret
--expand-data "{{fix:trim:url}}"
https://example.com/

Documented. Many new test cases.

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).
