This commit changes wxExecute() to handle SIGCHLD to be notified about the
child process termination instead of detecting when the file descriptor
corresponding to the other end of a pipe opened in the parent process was
closed in the child as this was not reliable and could (and did) result in not
detecting the termination of the child processes that closed all their file
descriptors before exiting.
This commit also removes a lot of platform-specific code duplicating the
generic event loop sources support and reuses it for wxExecute() purposes too.
Final big change is that wxEndProcessData was merged into wxExecuteData and we
don't have two similar but quite different classes any more but just one,
which is used both to pass the information from wxExecute() to wxAppTraits
methods and to store this information until the child termination.
Closes#10258.

Instead of hardcoding the call to WakeUpIdle() in the signal handler itself,
just wake up the event loop when we catch a signal. This will still result in
WakeUpIdle() being called, before the next event loop iteration, but it will
also allow us to do other things on wakeup from signal as it will be done in
the upcoming wxExecute() changes to support wxEXEC_NOEVENTS in console
applications.
See #10258.

as GSocket) which is a base class with various wxSocketImplXXX implementations
provided by different wxSocketManagers.
Share more code between ports (still not finished).
Refactor some code inside wxSocketImpl itself to be less redundant and fixed a
couple of minor bugs in the process.
