Merge branch 'PHP-8.3'

* PHP-8.3:
  Fix bug GH-15514 (Configure error: genif.sh: syntax error)

Autotools: Refactor main/internal_functions commands

This wraps generation of main/internal_functions* files into a separate
AC_CONFIG_COMMANDS and uses a SHELL variable instead of sh command.
Autoconf sets the SHELL variable to a suitable current shell the
configure is running in.

Instead of putting the commands into the 2nd argument the 3rd
initialization argument is used like before because it is easier to read
and work with variables (AWK, EXT_STATIC and EXT_CLI_STATIC), which
would need to be assigned again for the 2nd argument.

This simplifies the configure usage on Solaris 10 C shell and KornShell
without issuing errors when executing genif.sh script.
