Closes#20076
1. With `MBEDTLS_SSL_PROTO_TLS1_2` not enabled, the mbedTLS code was not
able to connect to any server due to broken logic in curl's
`mbed_set_ssl_version_min_max()`. Now it correctly sets the minimum
supported TLS version based on what is compiled in the library.
2. If debugging is enabled, move the debugging enabling earlier in the
`mbed_connect_step1()` so that verbose errors are actually displayed if
failures happen (see the previous point -- it would've made debugging
that issue easier).
3. Remove the constant `mbedtls_x509_crt_profile_fr` and instead use
mbedTLS-included profile `mbedtls_x509_crt_profile_next` with
`mbedtls_ssl_conf_cert_profile()`. This will follow the latest standards
as new mbedTLS versions are released (rather than being stuck-in-time
until someone comes along to fix what was hard-coded here). This has the
immediate benefit of no longer supporting SHA1 certs and insecure RSA
key-lengths (1024). This fix immediately prevents previously possible
MITM attacks (SHA1 hashes and RSA-1024 keys can be forged relatively
easily by nation-state actors and criminal organizations with
deep-pockets).
4. Added [predictive
resistance](https://mbed-tls.readthedocs.io/en/latest/kb/how-to/add-a-random-generator/#enabling-prediction-resistance)
to the random number generator (adding more entropy to the RNG).
5. Split the random number generator into initialization, the actual
random generation, and the "freeing" of the resources. This
significantly reduces the overhead of using the RNG.
6. Removed the separate RNG function in the TLS connect stage (instead
use the "main" one) and remove the ad-hoc threading support. Instead
properly document how to enable threading in mbedTLS. As it was, other
internals of mbedTLS could have race conditions (in the RSA module in
particular) if `MBEDTLS_THREADING_C` was *not* enabled. And if it is
enabled, then these race-conditions cannot happen. And also, if
MBEDTLS_THREADING_C is enabled then the RNG functions [are fully
thread-safe](https://mbed-tls.readthedocs.io/en/latest/kb/development/thread-safety-and-multi-threading/).
So, the previous ad-hoc threading support was both partial and broken.
7. Enable support for disabling `MBEDTLS_PEM_PARSE_C`.
8. Add support for `CURLOPT_SSLCERTTYPE` so user can specify `PEM` or
`DER` and get faster execution.
Closes#19983
Move existing `Curl_rename()` `rename()` wrapper from lib to
curlx/fopen, and make it a curlx macro/function. To allow using
the local worker function to fixup long filenames on Windows.
Then fix the Windows-specific rename implementation to support long
filenames. This operation may happen when using a cookie jar, HSTS cache
or alt-svc cache, via libcurl or the curl tool.
Before this patch, when passing a long filename to the above options,
a `<random>.tmp` file was left on the disk without renaming it to the
filename passed to curl. There was also 1 second delay for each
attempted rename operation.
Also:
- checksrc: ban raw `rename()` and `MoveFileEx*()` functions.
- Note: `Curl_rename()` returned 1 on failure before this patch, while
`curlx_rename()` returns -1 after, to match POSIX `rename()`.

It makes them work in Schannel's CA bundle loader, and curl tool's
set/get file timestamp operations (e.g. in `-R`/`--remote-time`). Also
to match file open operations, that already support long filenames.
E.g. when using `--remote-time`, fixing:
```
Warning: Failed to set filetime 1741363917 on outfile: CreateFile failed:
Warning: GetLastError 0x00000003
```
The special long filename logic is necessary to support Windows releases
prior to Windows 10 v1607. With the latter, it's possible to opt-in to
this behavior via a manifest setting. Note that Windows itself also needs
to opt-in to support this. Finally note that curl itself needs passing
`--globoff` to let long filenames through, pending #20044 and #20046.

Always use curlx_now() when calling Curl_pgrs_now(data). Tests with the
"manual" updates to now proved differ more then 100ms in parallel testing.
Add `curlx_nowp()` to set current time into a struct curltime.
Add `curlx_ptimediff_ms() and friends, passing pointers.
Update documentation.

- curl_setup.h: replace `if ! defined __LP64` with `ifndef __LP64`.
I assume it makes no difference on Tandem systems, as the latter form
is already used in `include/curl/system.h`.

Use `data->progress.now` as the timestamp of proecssing a transfer.
Update it on significant events and refrain from calling `curlx_now()`
in many places.
The problem this addresses is
a) calling curlx_now() has costs, depending on platform. Calling it
every time results in 25% increase `./runtest` duration on macOS.
b) we used to pass a `struct curltime *` around to save on calls, but
when some method directly use `curx_now()` and some use the passed
pointer, the transfer experienes non-linear time. This results in
timeline checks to report events in the wrong order.
By keeping a timestamp in the easy handle and updating it there, no
longer invoking `curlx_now()` in the "lower" methods, the transfer
can observer a steady clock progression.

To really verify the presence of the XML prolog, also in CI.
- move the prolog check from `loadtest` to `checktest`.
(load did a soft error, silently skipping the test instead of failing)
- runtests: enable `-w` functionality permanently for all test targets,
drop the option. It has no measurable performance impact.
- test 798, 1665: add XML prolog.

To detect mistakes made in the runtests framework that reduce
the number of test runs. Before this patch it could go undetected with
a green CI.
The minimum thresholds will need light maintenance going forward (either
bumping them periodically, or adjust if some may fell below minimums for
justified reasons). We may also make minimums tighter or looser, or more
job-specific.
Latest number of test runs for each job can be seen at Test Clutch:

Also:
- GHA: set minimums.
