Introduce convenience macros for copying flags that hold when concatenating two strings

This abstracts away, and cleans up, the flag handling for properties of
strings that hold when concatenating two strings if they both hold that
property. (These macros also work with simply copies of strings because
a copy of a string can be considered a concatenation with the empty
string.) This gets rid of some branches and some repetitive code, and
leaves room for adding more flags like these in the future.

Convert iterable into an internal alias for Traversable|array (#7309)

This does a compile time transformation of ``iterable`` into ``Traversable|array`` which simplifies some of the LSP variance handling.

The arginfo generation script from stubs is updated to produce a union type when it encounters the type ``iterable``
Extension functions which do not regenerate the arginfo, or write them manually are still supported by mimicking the compile time transformation while registering the function.

Type Reflection is preserved for single ``iterable`` (and ``?iterable``) to produce a ReflectionNamedType with name ``iterable``, however usage of ``iterable`` in union types will be converted to ``array|Traversable``

Eliminate duplicate code.

* Zend/zend_string: add zend_string_starts_with()

* ext/{opcache,phar,spl,standard}: use zend_string_starts_with()

This adds missing length checks to several callers, e.g. in
cache_script_in_shared_memory(). This is important when the
zend_string is shorter than the string parameter, when memcmp()
happens to check backwards; this can result in an out-of-bounds memory
access.

Trying to allocate a `zend_string` with a length only slighty smaller
than `SIZE_MAX` causes an integer overflow; we make sure that this
doesn't happen by catering to the maximal overhead of a `zend_string`.
