Fix GH-15980: Signed integer overflow in main/streams/streams.c

We need to avoid signed integer overflows which are undefined behavior.
We catch that, and set `offset` to `ZEND_LONG_MAX` (which is also the
largest value of `zend_off_t` on all platforms). Of course, after such
a seek a stream is no longer readable, but that matches the current
behavior for offsets near `ZEND_LONG_MAX`.

Closes GH-15989.

Fix GH-15908 and GH-15026: leak / assertion failure in streams.c

This was first reported as a leak in GH-15026, but was mistakingly
believed to be a false positive. Then an assertion was added and it got
triggered in GH-15908. This fixes the leak. Upon merging into master the
assertion should be removed as well.

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.

Fix GH-15712: overflow on float print with precision ini large value.

When allocating enough room for floats, the allocator used overflows with
large ndigits/EG(precision) value which used an signed integer to
increase the size of thebuffer.
Testing with the zend operator directly is enough to trigger
the issue rather than higher level math interface.
