Allow using readonly as function name

Don't treat "readonly" as a keyword if followed by "(". This
allows using it as a global function name. In particular, this
function has been used by WordPress.

This does not allow other uses of "readonly", in particular it
cannot be used as a class name, unlike "enum". The reason is that
we'd still have to recognize it as a keyword when using in a type
position:

class Test {
public ReadOnly $foo;
}

This should now be interpreted as a readonly property, not as a
read-write property with type `ReadOnly`. As such, a class with
name `ReadOnly`, while unambiguous in most other circumstances,
would not be usable as property or parameter type. For that
reason, we do not support it at all.

Fix static variable behavior with inheritance

When a method is inherited, the static variables will now always
use the initial values, rather than the values at the time of
inheritance. As such, behavior no longer depends on whether
inheritance happens before or after a method has been called.

This is implemented by always keeping static_variables as the
original values, and static_variables_ptr as the modified copy.

Closes GH-6705.
