Web UI: Remove redfishSupportEnabled

redfishSupportEnabled was a bit of a misnomer, because even if
set to false the Web UI user management continued to use Redfish.

The only place redfishSupportEnabled was used was the Redfish Event
Log page.

https://gerrit.openbmc-project.xyz/c/openbmc/phosphor-webui/+/22868
Renames Redfish Event Log support to redfishEventLogDisabled.
It is enabled by default/if undefined will be enabled.

Should wait for 22868 to merge.

Tested: Tested 22868 with undefined redfishEventLogDisabled
        and see panel in navigation.
