Fix several mostly Windows related phpdbg bugs
* Properly initialize PHPDBG_G(watch_tmp)
Otherwise that may cause segfaults in ZTS builds.
* Deactivate potentially remaining watchpoints after REPL
Otherwise the memory could still be protected, resulting in segfaults
during shutdown.
* NULL zend_handlers_table after freeing
As of commit 4130fe4[1], the `zend_handlers_table` is explicitly
freed in the `zend_vm_dtor()`. Since phpdbg (and maybe some other
SAPIs) may restart the engine afterwards, we have to make sure that
the table is also NULLed.
* Only set context option if there is a context
In other words, we must not follow the null pointer.
* Cater to file handles without attached console
File handles do not necessarily have an attached console (for
instance, pipes do not), in which case `GetConsoleScreenBufferInfo()`
fails. In this case we set a default value (`40`) for lines like on
other systems.
