drivers: ethernet: stm32: Updated original multicast hash filter change

 - Applied changes on the most recent version of the driver
 - Using CONFIG_ETH_MULTICAST_FILTER to enable/disable the hash filter
 - Using read-modify-write the hash table for a single address
when joining
 - When leaving rebuild the entire hash table and ensure that multicast
addresses used for the hash calcuation doesn't have the joined flag set

I have tested these conditions:
 - IGMP enabled and disabled on my ethernet network
 - Observed the network utilisation on a STM32H7 device running these
changes with the hash filter enabled and disabled while the device is
on a ethernet network with high rate multicast traffic
 - When the application closes a socket for a multicast receive, ensure
it doesn't affect the receiption of existing sockets as well as IGMP

Fixes #53773
