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.

Q: "The cmake build selected to run gcc with -fPIC on my box while the
plain configure script did not."
A: With CMake, since 2ebc74c36a19a1700af394c16855ce144d9878e3 #11546
and fc9bfb14520712672b4784e8b48256fb29204011 #11627, we explicitly
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.)

cmake: delete obsolete TODO items [ci skip]
There is always room for improvement, but CMake is up to par now with

Answering one of questions:
Q: "The gcc command line use neither -g nor any -O options. As a
developer, I also treasure our configure scripts's --enable-debug
option that sets a long range of "picky" compiler options."
A: CMake offers the `CMAKE_BUILD_TYPE` variable to control debug info
and optimization level. E.g.:
- `Release` = `-O3` + no debug info
- `MinSizeRel` = `-Os` + no debug info
- `Debug` = `-O0` + debug info

windows: use built-in `_WIN32` macro to detect Windows
Windows compilers define `_WIN32` automatically. Windows SDK headers
or build env defines `WIN32`, or we have to take care of it. The
agreement seems to be that `_WIN32` is the preferred practice here.
Make the source code rely on that to detect we're building for Windows.
Public `curl.h` was using `WIN32`, `__WIN32__` and `CURL_WIN32` for
Windows detection, next to the official `_WIN32`. After this patch it
only uses `_WIN32` for this. Also, make it stop defining `CURL_WIN32`.
There is a slight chance these break compatibility with Windows
compilers that fail to define `_WIN32`. I'm not aware of any obsolete
or modern compiler affected, but in case there is one, one possible
solution is to define this macro manually.
grepping for `WIN32` remains useful to discover Windows-specific code.
Also:
- extend `checksrc` to ensure we're not using `WIN32` anymore.
- apply minor formatting here and there.
- delete unnecessary checks for `!MSDOS` when `_WIN32` is present.
