Fix type info for pg_socket()

This was mistakenly changed to MAY_BE_OBJECT when pgsql was
migrated to use objects. However, this particular function
still returns a (stream) resource.

Add avif support to ext/gd

This backports avif support from upstream libgd into bundled libgd
and exposes the functionality through new imagecreatefromavif()
and imageavif() function

Look up func info using function name rather than lcname of call

As we already have the called zend_function here, let's use the
name directly, rather than using the lcname of the call.

As we already have the called zend_function here, let's use the

Remove FR/FX macros

Functions returning by-reference are generally a lost cause, we
won't be able to provide useful information for them.

Remove UNKNOWN_INFO func info entries

There's no need to explicitly list that we don't know anything
about a function -- that's the default state.

Fix pgsql func info

Some functions can now return a value with refcount > 1.

Remove unnecessary php.h includes from Zend/

The Zend/ directory really shouldn't be including php headers.
These particular includes are plain unnecessary.

Support prototypes in call graph

Even if we don't know the exact method being called, include it
in the call graph with the is_prototype flag. In particular, we
can still make use of return types from prototype methods, as
PHP 8 makes LSP violations a hard error.

Most other places are adjusted to skip calls with !is_prototype.
Maybe some of them would be fine, but ignoring them is conservative.
