Catch potential exceptions during to string conversion

As of PHP 7.4.0, exceptions are allowed to be thrown from inside
`__toString()` methods; we have to cater to that, and catch these
exceptions early.

Fix #79247: Garbage collecting variant objects segfaults

variant objects have no (declared) properties, so the `get_properties`
handlers returns a pointer to constant storage for efficiency reasons.
This pointer must not be returned from the `get_gc` handler, though;
instead we set up an own `get_gc` handler and return NULL from it, to
signal that there are no properties to collect.

Fix #78650: new COM Crash

As of PHP 7.4.0, the `get_property_ptr_ptr` handler is mandatory; we
implement it to always return `NULL`, which is equivalent to not
setting the handler in former versions.

We add a portable and faster test case than what has been presented in
the bug ticket.

Fix #77177: Serializing or unserializing COM objects crashes

Firstly, we avoid returning NULL from the get_property handler, but
instead return an empty HashTable, which already prevents the crashes.
Secondly, since (de-)serialization obviously makes no sense for COM,
DOTNET and VARIANT objects (at least with the current implementation),
we prohibit it right away.

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

Add _IS_NUMBER as cast_object() target type

convert_scalar_to_number() will now call cast_object() with an
_IS_NUMBER argument, in which case the cast handler should return
either an integer or floating point number, whichever is more
appropriate.

Previously convert_scalar_to_number() unconditionally converted
objects to integers instead.
