feat: Remove the SEND_CATALOG_INFO_SIGNAL

This setting controls an additive feature to send a signal on catalog
changes.  The signal is documented as a part of the list of supported
events in our openedx-events reference. It has also been running live in
the edx.org deployment for some time.

This change removes the signal and defaults to the behavior as if it is
net to true.

OPERATORS NOTE: If you override the `SEND_CATALOG_INFO_SIGNAL` in your
settings overrides for the edx-platform, you can remove that override.
This signal will always fire on catalog changes now.  The performance
impact of this change should be negligible.
