This commit removes code that only was being executed by php < 73
and it's 100% safe to do so because Moodle 3.11 and up require
php 73, hence it was not executed ever.
Removed code includes:
- ldap_control_paged_result and ldap_control_paged_result_response
(that were deprecated in php 73 and have been removed in php 80).
- conditional code in the session manager, where some hacks were
needed for php < 73. Note that this removes the private function
append_samesite_cookie_attribute() completely because it was
doinf nothing (first line was returning for php < 73).
- Also removed the old session.hash_function ini setting because
it was removed in php 71.
Kept code includes:
- The environmental check_igbinary322_version test has not been
removed because it doesn't hurt (always returns "ok" for php 73
sites) and doing it would involve to backport the environment.xml
file to 39 and 310. Instead, a note has been added to MDL-71747
in order to get rid of that check for 4.1 and up.
