Fix GH-15837: Segmentation fault in ext/simplexml/simplexml.c

We should check if the iterator data is still valid, because if it
isn't, then the type info is UNDEF, but the pointer value may be
dangling.

Fix GH-12929: SimpleXMLElement with stream_wrapper_register can segfault

Move SimpleXML invalidation code after node checks

This is safe, i.e. the tree hasn't been modified yet, because either we
didn't call a libxml modification function yet, or xmlNewChild is called
with a NULL pointer, which makes it bail out and return NULL.

Closes GH-12947.

Apply SimpleXML iterator fixes only on master

Many methods in SimpleXML reset the iterator when called. This has the
consequence that mixing these operations with loops can cause infinite
loops, or the loss of iteration data.
Some people may however rely on the resetting behaviour. To prevent
unintended breaks in stable branches, let's only apply the fix to master.

This reverts GH-12193, GH-12229, GG-12247 for stable branches while
keeping them on master, adding a note in UPGRADING as well.

Fix GH-12192: SimpleXML infinite loop when getName() is called within foreach

This happens because getName() resets the iterator to the start because
it overwrites the iterator data.

This happens because getName() resets the iterator to the start because
it overwrites the iterator data.
We add a version of get_first_node that does not overwrite the iterator
data.
