Fix Zend signals unblocking

There are a few parts here:
* opcache should not be blocking signals while invoking compile_file,
otherwise signals may remain blocked on a compile error. While at
it, also protect SHM memory during compile_file.
* We should deactivate Zend signals at the end of the request, to make
sure that we gracefully recover from a missing unblock and signals
don't remain blocked forever.
* We don't use a critical section in deactivation, because it should
not be necessary. Additionally we want to clean up the signal queue,
if it is non-empty.
* Enable SIGG(check) in debug builds so we notice issues in the future.

Fix issue with zend signals in php_request_startup

The zend_signals_activate() function is called in php_request_startup()
even if `--disable-zend-signals` is used. This causes uninitialized
variables to be used on ZTS builds.

This was removed in 7.1 in c870633. Removing guards from the SAPIs
should be fine, but removing the guard from main/main.c prevents anyone
using the static embedded library to integrate PHP into their programs.

Bug #74815 crash with a combination of INI entries at startup

TS related VCWD routines depend on CWD. Thus, a premature CWD
deactivation renders the VCWD layer unusable. Same issue seems to
persist in versions < 7.2, just that the code path is actually unused so
the issue didn't show up. Still might make sense to backport this into
lower branches.

Interned strings unification for TS/NTS

Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings

- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end

There is no runtime interning.

With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.

refactor php_win32_get_random_bytes(), take 2

As in previous variant, locking is removed and the initialization
is done only once at process start. The CNG API turns out to be
faster, also the initialization is less resources hungry. The
initialization part could need to be improved, if too much startup
failures are sighted in the real world usage. Though that would mean
having locking back.

The usage of CNG was already pointed out and requested in several
reports, with the further refactoring it appears to make sense and
simplify things a backward compatible way.

Revert "refactor php_win32_get_random_bytes()"

This reverts commit 23bd7bcde03c31e2678f23f12c72c96c24800c92.

Looks like this change is unstable. If same CSP is use but multiple processers,
the initialization failures are possible. Thus, CryptAcquireContext in
every process, even if it won't be used at all, is not sensible. This
might actually motivate to look for better CSP APIs.
