Avoid MSVC unused variable warning in FastZPP

MSVC doesn't support __attribute__((unused)), so this can cause

However, this requires us to initialize the variable as well,
to ensure that ubsan does not read a trap representation.

Deprecate passing null to non-nullable arg of internal function

This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.

This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

Added Inheritance Cache.

This is a new transparent technology that eliminates overhead of PHP class inheritance.

PHP classes are compiled and cached (by opcahce) separately, however their "linking" was done at run-time - on each request. The process of "linking" may involve a number of compatibility checks and borrowing methods/properties/constants form parent and traits. This takes significant time, but the result is the same on each request.

Inheritance Cache performs "linking" for unique set of all the depending classes (parent, interfaces, traits, property types, method types involved into compatibility checks) once and stores result in opcache shared memory. As a part of the this patch, I removed limitations for immutable classes (unresolved constants, typed properties and covariant type checks). So now all classes stored in opcache are "immutable". They may be lazily loaded into process memory, if necessary, but this usually occurs just once (on first linking).

The patch shows 8% improvement on Symphony "Hello World" app.

Remove Z_PARAM separate params where they don't make sense

Separation can only possibly make sense for array parameters

never makes sense to separate a bool.

The deref parameters are also of dubious utility, but leaving them

Make null byte error a ValueError

Currently we treat paths with null bytes as a TypeError, which is
incorrect, and rather inconsistent, as we treat empty paths as
ValueError. We do this because the error is generated by zpp and
it's easier to always throw TypeError there.

This changes the zpp implementation to throw a TypeError only if
the type is actually wrong and throw ValueError for null bytes.
The error message is also split accordingly, to be more precise.

Closes GH-6094.

Release call trampolines in zpp fcc

When using zpp 'f' or Z_PARAM_FUNC, if the fcc points to a call
trampoline release it immediately and force zend_call_function
to refetch it. This may require additional callability checks
if __call is used, but avoids the need to carefully free fcc
values in all internal functions -- in some cases this is not
simple, as a type error might be triggered by a later argument
in the same zpp call.

This fixes oss-fuzz #25390.

Rehash function table after disabling functions

To perform fast shutdown without full table cleanup we need all
internal functions to be in one continuous chunk. This was
violated when functions were deleted via disable_functions.

This drops the zend_disable_function() API in favor of
zend_disable_functions(), which disables the given list of
functions and performs the necessary rehash afterwards.

Also drop PG(disabled_functions), which is no longer used.
