Fix build

`accel_system_id` gas been renamed to `zend_system_id`.

Avoid OOB reads in create_name_with_username()

`accel_uname_id` and `zend_system_id` are MD5 buffers which are not
NUL terminated. Thus, we must not pass them to `snprintf()`.

Add system ID entropy API

The `zend_system_id` is a (true global) system ID that fingerprints a process state. When extensions add engine hooks during MINIT/startup, entropy is added the system ID for each hook. This allows extensions to identify that changes have been made to the engine since the last PHP process restart.

There are obviously issues with running tests in parallel, maybe
related to the cache ID. This needs to be investigated. Revert for
now.

Fix #79040: Warning Opcode handlers are unusable due to ASLR

We must not use the same shared memory OPcache instance for different
SAPIs, since their memory layout is different. To avoid this, we add
the SAPI name (truncated to at most 20 characters) to the names of the
memory base file, the mutex and the file mapping.

Fix ASLR related invalid opline handler issues

Opcache stores `opline->handler`s in shared memory. These pointers are
invalid, if the main PHP DLL is loaded at another base address due to
ASLR. We therefore store the address of `execute_ex` in the mmap base
file, and check on startup whether it matches its current address. If
not, we fall back on the file cache if enabled, and bail out otherwise.

This still does not address cases where the opline handler is located
inside of another DLL (e.g. for some profilers, debuggers), but there
seems to be no general solution for now.

Allow multiple cache instances per user/host on Windows

Formerly, there was at most a single OPcache instance per user and the
so called system ID (which is determined from the PHP version).
Sometimes multiple OPcaches might be desired, though, particularly for
unrelated CLI scripts, which may even be necessary (e.g. for our test
suite in parallel mode).

We therefore introduce a new INI directive `opcache.cache_id` which
allows to configure independent OPcache instances for the same user.

We also use `GetUserNameW()` instead of `php_win32_get_username()`,
because the latter retrieves the user name encoded in the
`default_charset`, which can obviously yield different results for
different charsets, leading to OPcache "incompatibilities". Slightly
worse, some characters may not even be encodeable in the
`default_charset` and would be replaced by question marks, which could
result in different users sharing the same OPcache.

We also refactor, and re-use existing APIs to avoid duplicated code.

The FormatMessage API needs to LocalFree the delivered error messages.
In cases where messages are delivered in non ASCII compatible encoding,
the messages might be unreadable. This aligns the error message encoding

Use string literal as format

Fixed "opcache.file_cache_fallback" mode.

It's not safe to change value of ZCG(accel_directives).file_cache_only, becuse it might be altered by INI subsystem.
Use global variable instead.
