Fix ZTS crashes with persistent resources in modules (#13381)

On shutdown in ZTS the following happens:
- https://github.com/php/php-src/blob/master/Zend/zend.c#L1124-L1125
gets executed. This destroys global persistent resources and destroys
the modules. Furthermore, the modules are unloaded too.
- Further down, `ts_free_id(executor_globals_id)` gets executed, which
calls `executor_globals_dtor`. This function destroys persistent
resources for each thread.

Notice that in the last step, the modules that the persistent resource
belong to may already have been destroyed. This means that accessing
globals will cause a crash (I previously fixed this with ifdef magic),
or when the module is dynamically loaded we'll try jumping to a
destructor that is no longer loaded in memory. These scenarios cause
crashes.

It's not possible to move the `ts_free_id` call upwards, because that
may break assumptions of callers, and furthermore this would deallocate
the executor globals structure, which means that any access to those
will cause a segfault.

This patch adds a new API to the TSRM that allows running a callback on
a certain resource type. We use this API to destroy the persistent
resources in all threads prior to the module destruction, and keep the
rest of the resource dtor intact.

I verified this fix on Apache with postgres, both dynamically and
statically.

Fixes GH-12974.

Fix GH-12974: Apache crashes on shutdown when using pg_pconnect()

On ZTS, the global variables are stored in dynamically allocated memory.
When the module gets shut down this memory is released. After the module
is shut down, only then are the persistent resources cleared. Normally
this isn't an issue, but pgsql and odbc refer to the globals to modify
some counters, after the globals have been freed.
Fix this by guarding the modification.

Closes GH-13032.

PGSQL: Allow unconditional selection in pg_select

Previously, pg_select did not allow unconditional selection, where an
empty ids array would result in a function failure.

This patch implements two changes:
- Make the ids array an optional parameter.
- Allow the ids array to be empty.

In both cases, unconditional selection happen, which is equivalent to
pg_query('SELECT * FROM <table>;').

Two test cases were added to test the aforementioned changes.
