Subject: [PATCH] Default initialise is_handle_internal_

gcc12 flags `is_handle_internal_` as maybe being uninitialised. This PR adds a default initialisation for `is_handle_internal_` to avoid this.
```
/usr/local/include/mio/detail/mmap.ipp:419:8: warning: '<anonymous>.mio::basic_mmap<mio::access_mode::write, char>::is_handle_internal_' may be used uninitialized [-Wmaybe-uninitialized]
  419 |     if(is_handle_internal_)
      |        ^~~~~~~~~~~~~~~~~~~
```
