Fix and undeprecate ReflectionType::__toString()

Add deprecated _ZendTestClass::__toString() method to preserve
an existing test.

ReflectionType::__toString() will now return a complete
representation of the type, as it should have originally. Users
that relied on nullability being absent should have been pushed
to ReflectionNamedType::getName() by the deprecation of
ReflectionType::__toString() in PHP 7.1 / PHP 7.4.

Remove mention of PHP major version in Copyright headers

Add check_only parameter to get_closure handler

`get_closure` handlers are called to check whether an object is
callable, and to actually get the closure, respectively. The behavior
of the handler might differ for these two cases, particularly the
handler may throw in the latter case, but should not in the former.

Therefore we add a `check_only` parameter, to be able to distinguish
the desired purpose.

Use ZEND_TYPE_IS_SET() when checking for property types

Instead of a simple if or 0 comparison. This would no longer work
if zend_type is a struct.

Don't set nullability flag for parameters without type

Don't set nullability flag for parameters without type

Use value 0 instead. To compensate we check in ReflectionParameter
allowsNull() whether the type is set at all: If it isn't, it always
allows null.

This removes a discrepancy between internal&userland functions:
For userland functions allowsNull() on untyped parameters returned
true, but for internal functions it returned false.

Standardize type printing in reflection

Use ?T instead of "T or NULL".

Change representation of zend_type from type code to MAY_BE_* mask

This switches zend_type from storing a single IS_* type code to

Change representation of zend_type from type code to MAY_BE_* mask

This switches zend_type from storing a single IS_* type code to
storing a MAY_BE_* type mask. Right now most code still assumes
that there is only a single type in the mask (or two together
with MAY_BE_NULL). But this will make it a lot simpler to introduce
union types.

An additional advantage (and why I'm doing this separately), is
that a number of special cases no longer need to be handled
separately: We can do a single mask & (1 << type) check to handle
all simple types, booleans (true|false) and null.

Make ReflectionType an abstract class

Move isBuiltin() method from ReflectionType to ReflectionNamedType

This method only makes sense for single types, e.g. it would be

Note that we always return ReflectionNamedType right now, so this does
not break compatibility for code using any currently existing types.
