[skip ci] Mention AVX(2) detection fix for MSVC in UPGRADING

This is likely more important than the possibility to build for AVX-512
since our official binaries have build time support for SSE2 only. So
proper detection of AVX may make a huge performance difference for
`base64_*()` and some MBString functionality.

Closes GH-16248.

libcurl ref: [`CURLINFO_POSTTRANSFER_TIME_T`](https://curl.se/libcurl/c/CURLINFO_POSTTRANSFER_TIME_T.html)

`CURLINFO_POSTTRANSFER_TIME_T` is a libcurl info option that returns
the time it took to "post" the transfer. Available since libcurl 8.10.0

This value is also exposed as `posttransfer_time_us` in the
`curl_getinfo()` return value when the `$option` parameter is not
passed.

ext/curl: Add `CURLOPT_DEBUGFUNCTION` option (GH-15674)

ext/curl: Add `CURLOPT_DEBUGFUNCTION` option (GH-15674)

This adds support for `CURLOPT_DEBUGFUNCTION`[^1] Curl option to set a
custom callback that gets called with debug information during the
lifetime of a Curl request.

The callback gets called with the `CurlHandle` object, an integer
containing the type of the debug message, and a string containing the
debug message. The callback may get called multiple times with the
same message type during a request.

PHP already uses `CURLOPT_DEBUGFUNCTION` functionality to internally
to expose a Curl option named `CURLINFO_HEADER_OUT`.

However,`CURLINFO_HEADER_OUT` is not a "real" Curl option supported
by libcurl. Back in 2006, `CURLINFO_HEADER_OUT` was added[^2] as
a Curl option by using the debug-callback feature. Git history does
not run that back to show why `CURLINFO_HEADER_OUT` was added as a
Curl option, and why the other debug types (such as
`CURLINFO_HEADER_IN` were not added as Curl options, but this seems
to be a historical artifact when we added features without trying
to be close to libcurl options.

This approach has a few issues:

1. `CURLINFO_HEADER_OUT` is not an actual Curl option supported by
upstream libcurl.

2. All of the Curl options have `CURLOPT_` prefix, and `CURLINFO_HEADER_OUT`
is the only Curl "option" that uses the `CURLINFO` prefix. This exception
is, however, noted[^3] in docs.

3. When `CURLINFO_HEADER_OUT` is set, the `CURLOPT_VERBOSE` is also implicitly
set. This was reported[^4] to bugs.php.net, but the bug is marked as wontfix.

This commit adds support for `CURLOPT_DEBUGFUNCTION`. It extends the existing
`curl_debug` callback to store the header-in information if it encounters
a debug message with `CURLINFO_HEADER_OUT`. In all cases, if a callable
is set, it gets called.

`CURLOPT_DEBUGFUNCTION` intends to replace `CURLINFO_HEADER_OUT` Curl
option as a versatile alternative that can also be used to extract
other debug information such as SSL data, text information messages,
incoming headers, as well as headers sent out (which `CURLINFO_HEADER_OUT`
makes available).

The callables are allowed to throw exceptions, but the return values are
ignored.

`CURLOPT_DEBUGFUNCTION` requires `CURLOPT_VERBOSE` enabled, and setting
`CURLOPT_DEBUGFUNCTION` does _not_ implicitly enable `CURLOPT_VERBOSE`.

If the `CURLOPT_DEBUGFUNCTION` option is set, setting `CURLINFO_HEADER_OUT`
throws a `ValueError` exception. Setting `CURLOPT_DEBUGFUNCTION` _after_
enabling `CURLINFO_HEADER_OUT` is allowed. Technically, it is possible
for both functionality (calling user-provided callback _and_ storing
header-out data) is possible, setting `CURLINFO_HEADER_OUT` is not
allowed to encourage the use of `CURLOPT_DEBUGFUNCTION` function.

This commit also adds the rest of the `CURLINFO_` constants used as
the `type` integer value in `CURLOPT_DEBUGFUNCTION` callback.

ext/mbstring: Update to Unicode 16

Updates UCD to Unicode 16.0 (released 2024 Sept).

Previously: 0fdffc18, #7502, #14680

Unicode 16 adds several new character sets and case folding rules.
However, the existing ucgendat script can still parse them.

This also adds a couple test cases to make sure the new rules for
East Asian Wide characters and case folding work correctly. These
tests fail on Unicode 15.1 and older because those verisons do not
contain those rules.

Add `ReflectionProperty::isDynamic()` as an alternative to `isDefault()` (#15758)

Dynamic properties are generally referred to as "dynamic" properties, while
non-dynamic properties are not commonly referred to as "default" properties.
Thus, the existing method `ReflectionProperty::isDefault()` has a non obvious
name; while an alias could be added for `isNotDynamic()`, a new `isDynamic()`
method seems cleaner. The new method returns the opposite of `isDefault()`;
dynamic properties are not present on the class by default, and properties
present by default are not added dynamically.
