Skip validity and length calls when the byte cannot be part of a multibyte sequence

Almost every character set can be given a number N such that a multibyte
sequence starts with a byte higher than that number N. This allows us to
skip a lot of work. To ensure the correctness of this, a sanity check is
implemented that exhaustively tries every 4-byte sequence for every
character set and checks for consistency issues.

This finally gives:
Time (mean ± σ): 120.2 ms ± 1.2 ms [User: 116.9 ms, System: 2.8 ms]
Range (min … max): 118.0 ms … 122.9 ms 24 runs

Move fetch_all implementation out of mysqlnd

There doesn't seem to be any compelling reason to implement this
in mysqlnd rather than mysqli. It's just a loop over fetch_into.

This makes the function available under libmysqlclient as well,
and thus fixes bug #79372.

PDO MySQL: Use native types for results

Previously, PDO MySQL only fetched data as native int/float if
native prepared statements were used. This patch updates PDO to
have the same behavior for emulated prepared statements, and thus
removes the largest remaining discrepancy between these two modes.

Note that PDO already has a ATTR_STRINGIFY_FETCHES option to control
whether native types are desired or not. The previous output can
be restored by enabling this option.

Most of the tests make use of that option, because this allows the
tests to work under libmysqlclient as well, which currently always
returns string results (independently of whether native or emulated
PS are used).

MySQLnd: Clean up and optimize mysqlnd result set handling

This is a larger overhaul of the mysqlnd result set infrastructure:

* Drop support for two different types of buffered results sets
("c" and "zval"). Possibly these made sense at some earlier
time, but now (with minor adjustments) one option is strictly
worse than the other. Buffered result sets already buffer the
full row packets, from which zvals can be decoded. The "zval"
style additionally also buffered the decoded zvals. As result
sets, even buffered ones, are generally only traversed once,
this just ends up wasting memory. Now, a potentially useful
variation here would be to buffer the decoded zvals instead of
the row packets, but that's not what the code was doing.
* To make it really strictly better, pre-allocate the zval row
buffer and reuse it for all rows. Previously the "c" style always
allocated a new buffer for each row.
* The fetch_row API now provides a populated zval[]. The task of
populating an array is deferred to fetch_row_into, which also
avoids duplicating this code in multiple places. The fetch_row_c
API is also implemented on top of fetch_row now, rather than
duplicating large parts of the code.
* The row fetching code for prepared statements and normal result
sets has been mostly merged. These already used the same
infrastructure, but prepared statements used separate row
fetching functions that were nearly the same as the normal ones.
This requires passing the stmt into the result set, rather than
just a flag. The only part that remains separate is reading of
unbuffered results in the presence of PS cursors.

Sync mysqlnd version with PHP version

Since mysqlnd is solely developed in the php-src repository, it makes
not much sense to have its own version number, particularly since
nobody cares to update it. Therefore we use PHP's version number, but
stick with the "mysqlnd" prefix which can be important to distinguish
the mysqli driver (libmysqlclient vs. mysqlnd).
