build: improve OS string in CMake and `config-win32.h`

This patch makes CMake fill the "OS string" with the value of
`CMAKE_C_COMPILER_TARGET`, if passed. This typically contains a triplet,
the same we can pass to `./configure` via `--host=`.

For non-CMake, non-autotools, Windows builds, this patch adds the ability
to override the default `OS` value in `lib/config-win32.h`.

With these its possible to get the same OS string across the three build
systems.

This patch supersedes the earlier, partial, CMake-only solution:
435f395f3f8c11eebfcc243ca55ebcc11a19b8b8, thus retiring the
`CURL_OS_SUFFIX` CMake option.

Makefile.m32: add `CURL_RC` and `CURL_STRIP` variables [ci skip]

They allow to override the hardcoded values for the `windres` and `strip`
tools, complementing the existing set of `CURL_{CC,AR,RANLIB}` variables.

`CURL_RC` comes handy when using LLVM tools with `CROSSPREFIX=llvm-` and
`CURL_CC=clang` set on current latest debian:unstable or earlier, where
`llvm-windres` is missing, and a `CURL_RC=<triplet>-windres` fixes it.
Hopefully this will be fixed in the llvm package. FWIW `llvm-windres`
does exist in Homebrew llvm, MSYS2 llvm and llvm-mingw.

openssl: add `CURL_BORINGSSL_VERSION` to identify BoringSSL

BoringSSL doesn't keep a version number, and doesn't self-identify itself
via any other revision number via its own headers. We can identify
BoringSSL revisions by their commit hash. This hash is typically known by
the builder. This patch adds a way to pass this hash to libcurl, so that
it can display in the curl version string:

For example:

`CFLAGS=-DCURL_BORINGSSL_VERSION="c239ffd0"`

```
curl 7.84.0 (x86_64-w64-mingw32) libcurl/7.84.0 BoringSSL/c239ffd0 (Schannel) zlib/1.2.12 [...]
Release-Date: 2022-06-27
Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap ldaps mqtt pop3 [...]
Features: alt-svc AsynchDNS brotli gsasl HSTS HTTP2 HTTP3 HTTPS-proxy IDN IPv6 Kerberos [...]
```

The setting is optional, and if not passed, BoringSSL will appear without
a version number, like before this patch.
