mprintf: overhaul and bugfixes
In a test case using lots of snprintf() calls using many commonly used
%-codes per call, this version is around 30% faster than previous
version.
It also fixes the #12561 bug which made it not behave correctly when
given unknown %-sequences. Fixing that flaw required a different take on
the problem, which resulted in the new two-arrays model.
lib557: extended - Verify the #12561 fix and test more printf features
unit1398: fix test: It used a <num>$ only for one argument, which is not
supported.

appveyor: replace PowerShell with bash + parallel autotools
PowerShell works (after a steep development curve), but one property of
it stuck and kept causing unresolvable usability issues: With
`$ErrorActionPreference=Stop`, it does abort on failures, but shows only
the first line of the error message. In `Continue` mode, it shows the
full error message, but doesn't stop on all errors. Another issue is
PowerShell considering any stderr output as if the command failed (this
has been improved in 7.2 (2021-Nov), but fixed versions aren't running
in CI and will not be for a long time in all test images.)
Thus, we're going with bash.
Also:
- use `-j2` with autotools tests, making them finish 5-15 minutes per
job faster.
- omit `POSIX_PATH_PREFIX`.
- use `WINDIR`.
- prefer forward slashes.
Fix remaining warnings in examples and tests which are not suppressed
by the pragma in `lib/curl_setup.h`.

Align mingw with the other Windows compilers and use the `int` type for
`CURL_TYPEOF_CURL_SOCKLEN_T` (and thus for `curl_socklent_t`). This
makes it unnecessary to make a mingw-specific trick and pull all Windows
headers early just for this type definition. This type is specific to
Windows, not to the compiler. mingw-w64's Windows header maps it to
`int` too.
With this we also delete all remaining uses of `CURL_PULL_WS2TCPIP_H`.

readwrite_data: loop less
This function is made to loop in order to drain incoming data
faster. Completely removing the loop has a measerably negative impact on
transfer speeds.
Downsides with the looping include
- it might call the progress callback much more seldom. Especially if
the write callback is slow.
- rate limiting becomes less exact
- a single transfer might "starve out" other parallel transfers
- QUIC timers for other connections can't be maintained correctly
The long term fix should be to remove the loop and optimize coming back
to avoid the transfer speed penalty.
This fix lower the max loop count to reduce the starvation problem, and
avoids the loop completely for when rate-limiting is in progress.

enable PIC for libcurl shared lib. Or when building libcurl for
shared and static lib in a single pass. We do this by default for
Windows or when enabled by the user via `SHARE_LIB_OBJECT`.
Otherwise we don't touch this setting. Meaning the default set by
CMake (if any) or the toolchain is used. On Debian Bookworm, this
means that PIC is disabled for static libs by default. Some platforms
(like macOS), has PIC enabled by default.
autotools supports the double-pass mode only, and in that case
CMake seems to match PIC behaviour now (as tested on Linux with gcc.)
