spacecheck.pl: drop more exceptions
- replace ß (scharfes S) with links.
- replace § (section sign) with links.
- replace 🙏 emoji with `:pray:`.
Supported by GitHub, Forgejo/Gitea and most likely GitLab.
- docs/libcurl/curl_mprintf.md: replace Unicode ± with `{+|-}`.
- docs/CIPHERS.md: URL encode Unicode in URLs.
- lib1560: use hex encoding in `räksmörgås.se`.
- unit1307: use hex encoding in `Lindmätarv`.
- drop LATIN SMALL LETTER A WITH ACUTE exception.
No longer appears in tests.
This leaves the single character exception: `ö`
And file exceptions holding contributor names.

setopt: provide info for CURLE_BAD_FUNCTION_ARGUMENT
If CURLE_BAD_FUNCTION_ARGUMENT is returned and failf() has not provided
any details, this adds a generic error string that includes the option
number.
This helps debugging for example the curl tool which does a lot of
setopt calls and in reading post fact logs it is not always easy to tell
exactly which call that failed.

cmake: test integration with old cmake (v3.11.4 2018-03-28)
Tests with old cmake are slow. (no Ninja, no unity, and running slower
than recent versions.)
It also revealed that 3.7.2 2017-01-13 is too old to consume curl via
`find_package()` due to:
```
CMake Error at bld-curl/_pkg/lib/cmake/CURL/CURLConfig.cmake:69 (add_library):
add_library cannot create ALIAS target "CURL::libcurl" because target
"CURL::libcurl_shared" is IMPORTED.

The mitigation for this issue requires 3.11.

- rename a few existing envs to use the `TEST_` prefix.
- make the `find_package` test provider stage verbose.
- fix issue when consuming with cmake 3.7.2 (all platforms):

curlx: move into to curlx/
Move curlx_ functions into its own subdir.
The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.
The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.
The strcase defines are not curlx_ functions and should not be used by
tool or server code.
dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.
When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.

generate.bat: exclude curlinfo.c from legacy VS projects
- Do not include curlinfo.c as a ClCompile unit when compiling the curl
tool.
Prior to this change generate.bat would add curlinfo.c to the source
files for the curl tool because it is located in the src directory. That
caused ambiguous behavior in legacy versions of Visual Studio which had
to guess between two main entry points (one in curlinfo and one in
tool_main, the latter being correct).

GHA: drop vcpkg cache and most vcpkg logic with it
The unplanned dropping of the granular vcpkg binary cache indeed fell
into the cracks between Microsoft's various departments. The old method
is now official dropped, without replacement either on the vcpkg side or
the GitHub cache provider side.
Without a granular cache, vcpkg is impractical for builds larger than
a small dependency tree in CI, for performance reasons.
A granular cache is critical for CI use. Building dependencies is not
a goal of this CI, so a more desirable option would be pre-built binary
downloads. This would also allow keeping job timeouts low, which is
important for quick iteration in GHA when a flaky job requiring a manual
retry needs all other jobs to finish first. (GHA often disregards
step timeouts, which is another contributing factor here.)
Windows remains tested extensively with MSYS2, curl-for-win, and via
AppVeyor CI with MSVC + OpenSSL, and also in GHA via scaled back vcpkg
jobs that perform well without caching. What's lost is the recently
added Android OpenSSL build tests.
We may consider building/cachine important dependencies manually as in
GHA/linux-http3, and/or try integrating MSVC jobs with MSYS2 UCRT DLLs.
