ext/mbstring: Always throw ValueErrors for invalid mb_http_input() type

[sodium] Add AEGIS-128L and AEGIS-256 (#12867)

Also don't prevent usage of AES-GCM on aarch64, it's been supported since libsodium 1.0.18.

Fixes #12312

Fix GH-12727: NumberFormatter constructor throws an exception on invalid locale.

Also re-establishing exception throwing on IntlDateFormatter constructor
overwritten by accident most likely so postponing it for next major
release.

Handle libxml2 OOM more consistently (#11927)

This is a continuation of commit c2a58ab07d, in which several OOM error
handling was converted to throwing an INVALID_STATE_ERR DOMException.
Some places were missed and they still returned false without an
exception, or threw a PHP_ERR DOMException.
Convert all of these to INVALID_STATE_ERR DOMExceptions. This also
reduces confusion of users going through documentation [1].

Unfortunately, not all node creations are checked for a NULL pointer.
Some places therefore will not do anything if an OOM occurs (well,
except crash).
On the one hand it's nice to handle these OOM cases.
On the other hand, this adds some complexity and it's very unlikely to
happen in the real world. But then again, "unlikely" situations have
caused trouble before. Ideally all cases should be checked.

Improve performance of mbfl_name2encoding() by using perfect hashing (#12707)

mbfl_name2encoding() uses a linear loop through the encodings, comparing
the name one by one, which is very slow. For the benchmark [1] just
looking up the name takes about 50% of run-time.

By using perfect hashing instead, we no longer have to loop over the
list, and the number of string comparisons is reduced to just a single
one. The perfect hashing table is generated using GNU gperf and amended
manually to fit in with mbstring and manually changed to reduce the
cache size.
