Fix bug #81472: Support large device major/minor number

Latest linux kernel use large number (12 bits for major device, 20
bits for minor device). Current code only supports previous standard
(5 chars), which means 8 bits for major and 8 bits for minor device.
It will fail if device number is out of that range. So this patch
increases device number read from /proc/self/maps file.

Closes GH-7512.

Fix multiple trait fixup

If a trait method is inherited, preloading trait fixup might be
performed on it multiple times. Usually this is fine, because
the opcodes pointer will have already been updated, and will thus
not be found in the xlat table.

However, it can happen that the new opcodes pointer is the same
as one of the old opcodes pointers, if the pointer has been reused
by the allocator. In this case we will look up the wrong op array
and overwrite the trait method with an unrelated trait method.

We fix this by indexing the xlat table not by the opcodes pointer,
but by the refcount pointer. The refcount pointer is not changed
during optimization, and accurately represents which op arrays
should use the same opcodes.

Fixes bug #80307. The test case does not reproduce the bug, because
this depends on a lot of "luck" with the allocator. The test case
merely illustrates a case where orig_op_array would have been NULL
in the original code.

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.
